Apparatus and Services
- Do not use apparatus without first reading instructions and then only if you understand its operation.
- Turn of all gas, water and electric supplies when they are no longer needed. Remember that a natural gas flame may be invisible in sunlight.
- Do not interfere with safety guards or electrics on apparatus.
- Do not overload benches, trolleys, lifts etc.
- Do not overload electrical supplies. Double adaptors are not recommended.
- Use appropriate protective clothing (eye shields, gloves, coats ) where this is recommended. Appropriate eye protection must be worn when handling lasers.

Electrical supplies and equipment can cause injury and even death as well as starting fires and explosions. High voltage experimental apparatus is especially dangerous. Test equipment carefully to ensure that it is functioning properly. If in doubt get it checked out by your supervisor or the workshop manager. It is good preventative maintenance to organise a regular inspection and testing of all electrical equipment in the laboratory. If in the laboratory, there are electrical cables that have power connections in the state shown then these leads must be taken out of service until repaired or replaced.
All new equipment should be inspected before it is used. This is especially important for equipment imported from overseas, which may not conform to Australian specifications with regard to electrical safety.
It is common in the laboratory to modify equipment or to design and construct electrical equipment for a special purpose. The laboratory supervisor should keep fully documented circuit diagrams or details of modifications to this type of equipment. This equipment should be inspected by an authorised person to ensure that electrical safety is not compromised.
General purpose electrical outlets in laboratories should be installed and repaired by a licensed electrician. Unsafe units should not be used and should be ‘Tagged’ until they are repaired or removed. All outlets should comply with AS 3112 or AS 3109.
All extension cords should comply with AS 3191. If there is a shortage of power points, the continual use of power boards and extension cords should be discouraged. The installation of more power outlets is a better and safer alternative. When using power boards and extension cables:
- Make sure that the power rating is not exceeded
- do not use extension leads in a coiled condition or when stored on a reel – they may overheat, resulting in damage to the insulation which in turn may lead to an electric shock or fire.
The smallest current which can be detected through skin is about 1 mA. Increasing current beyond 20 mA brings danger to life. Current passing through a part of the body, such as a finger, will not necessarily result in electric shock but may cause severe internal burns. All electrical burns need medical treatment.
If there is an accident act quickly. Switch off the electrical supply before removing the casualty. Avoid becoming a second victim yourself. If breathing has stopped artificial respiration must begin AT ONCE (see First Aid, page 14).
When equipment is not in use, and does not require power to maintain calibration or accuracy, the equipment should be turned off and the plug removed from the power socket. When equipment is in use and a fault is observed, report the problem immediately. This equipment should then be ‘Tagged’ and removed from service until the problem has been rectified.

AS 2243.7 – 1991 Safety in laboratories – electrical aspects
AS 3112 – 1990 Approval and test specification – Plugs and socket outlets
Never use defective tools, for example those with broken handles, chisels with mushroom heads, spanners with spread jaws, files without handles (especially on the lathe) and tools of the wrong size for the job.
Many accidents are caused by the operation of inadequately guarded machines or where the guards supplied have been removed irresponsibly. Your personal safety is largely dependent on the attitude you adopt towards the use and the maintenance of the safety guards and devices supplied.
Ergonomics is a specialised subject, therefore these guidelines can only outline the basic principles which should be followed when purchasing new furniture and in the planning stage for new accommodation. These guidelines will also be of use in an initial assessment of workstations or when problems arise. Further details can be obtained from Australian Standard As 3590 Part 2. Advice and assistance relating to specific problems may be obtained by contacting the Risk Management Office extn. 7075 or 6030.
Desk – Workstation
Basic considerations are:
- Is the height of the desk top surface between 680 mm -700 mm or is the desk top fully adjustable?
- Maximum bench thickness; 25 mm.
- Bench/Desk top surface depth minimum 900 mm for VDU use, 750 mm for administrative/clerical work without VDU.
- Leg space minimum of 800 mm width, 450 mm deep.
- Is the surface a neutral colour and non-reflective?
Basic considerations are :
- Effective seat depth adjustable from 380 mm to 480 mm?
- Seat height adjustment made easily while in use?
- Seat height adjustable 370 mm to 520 mm?
- Vertical convexity of lumbar support area approximately 250 mm radius? Lumbar support area between 200 mm and 250 mm top to bottom?
- Backrest width between 360 mm and 400 mm?
- Is height of lumbar support adjustable from 170 mm to 250 mm above the seat?
Screen Based Equipment
Major considerations for placement of screens are avoidance of glare and reflections. Basic considerations are :
- Do not place screen and operator in a position facing the window.
- Do not face screen towards window or have window behind operator.
- Site screen so that overhead luminaries are directly to the side of the screen.
- Place screen in front of operator and centre of screen about 15 degrees below the horizontal. The top of the screen should not be above eye height.
Fire and Explosion
A large proportion of all fires are electrical in origin. Common causes include: over-loaded or loose wires and cables, interference to air flows, covering hot surfaces, incorrect fuses. Explosions may be caused by sparks from switches, motors.
Before beginning work, find out where the master switch is located.
All electrical equipment must be regularly inspected
POTENTIAL HAZARDS OF COMPRESSED GASES
In a laboratory, compressed gas in cylinders is used for a number of processes, such as cooling, welding, aerating, adjuncts to automated analytical equipment, research tools and in anaerobic incubators.
The potential hazards associated with the use of compressed gas include a build-up of pressure in the cylinder, leading to an explosion and fire if the cylinder ruptures, and gas leaking out of the cylinder leading to toxic fumes in the workplace or an increased fire risk.
Material Safety Data Sheets should be readily available for all gases used in the laboratory and should be read and understood by all workers before they use the particular gas.
Only equipment specifically designed for gas cylinders, such as hoses, regulators and valves, should be used and only after it is certain that it is the correct device for the cylinder in question. If doubts exist over the suitability of these devices, advice should be sought from the supplier.
CLASSIFICATION OF GASES
Compressed gases are classified as Class 2 Dangerous Goods. This class is further subdivided into the following:
2.1 Flammable gases . These cylinders are labelled with a red dangerous goods diamond to signify the flammability hazard. Examples of these gases are acetylene, butane, carbon monoxide, hydrogen and propane.
2.2 Non-flammable and non-toxic gases. These cylinders are labelled with a green dangerous goods diamond to indicate their state. Examples of these gases include helium, argon, carbon dioxide, nitrogen, neon and krypton.
2.3 Poisonous gases. These cylinders are labelled with a white dangerous goods diamond to indicate their toxic properties. Examples of these gases include ammonia, chlorine, fluorine, phosgene, sulphur dioxide, nitric oxide and silane.
Some gases present more than a single hazard and these subsidiary risks are indicated by a second diamond, such as carbon monoxide
2.1 red diamond indicating flammability as the main hazard and
2.3 white diamond indicating toxicity as the subsidiary risk. Other
examples include chlorine 2.3 and 5.1 indicating toxicity and an oxidising agent, hydrogen chloride 2.3 and 8 indicating toxicity and corrosive properties and liquid oxygen 2.2 and 5.1 indicating that it is non-toxic and an oxidising agent.
IDENTIFICATION OF GAS CYLINDERS
All gas cylinders should be labelled so that their contents may be positively identified. If a cylinder is not clearly labelled, it should not be used and should be returned to the supplier. If this is not possible, the relevant Statutory Authority should be notified and advice sought on the best method of disposal.
The labelling and colour coding of gas cylinders should comply with AS 2992, AS 1942, AS 1943 and AS 1944. The following information is usually available on the label:
- identity of the contents;
- grade or purity of the gas;
- United Nations number, referring to the universal numbering system for safe handling, transport and storage of dangerous goods;
- HAZCHEM Emergency Code which refers to an action code for fire or major spills;
- Dangerous Goods diamond/s referring to the main and subsidiary hazards;
- summary of main hazards and safety instructions;
- contents of cylinder at normal temperature and pressure;
- nominal filling pressure at standard conditions (if applicable);
- name, address and telephone number of supplier;
- emergency telephone numbers; and
- other information such as the gas supplier and cylinder size codes.
STORAGE OF GAS CYLINDERS
Gas cylinders are often found within the laboratory and are regularly used in day-to-day processes. The number of cylinders stored inside a laboratory should be minimal and, if possible, gases that are regularly used should be piped into the laboratory rather than stored in cylinders. The area should be well ventilated and the fire risk minimised. Cylinders should be secured to the bench or wall with an appropriate restraining device to prevent them from falling.
Securing of gas cylinders
If gases are purchased in large quantities or if cylinders are not used regularly, they should be stored in a specifically designed gas storage area. Each State and Territory has statutory requirements dealing with the design and conditions for a specialised gas storage area. As a minimum, such stores should be:
- certified by the Statutory Authority if required;
- constructed of fire-rated material and have adequate fire separation between each of the Class 2 Dangerous Goods categories;
- well ventilated and away from the main buildings;
- free from fire risks, with markings indicating “no smoking” and “no naked flames”
- marked with the appropriate Dangerous Goods and HAZCHEM labelling;
- secure and access restricted to authorised personnel;
- provided with the appropriate fire fighting and emergency equipment;
- ·provided with a means of securing cylinders in an upright position; and
- able to segregate between empty and full cylinders.</li/>
Persons dealing with the gas store should be trained in the safe operation of the store, the use of emergency equipment, the location and interpretation of the Material Safety Data Sheets and safe handling techniques for moving cylinders.
SAFE HANDLING OF GAS CYLINDERS
The majority of accidents with gas cylinders occur while moving the cylinder from one place to another. Trolleys or other suitable devices should be available for safe transport of cylinders, even if for a short distance, and persons should be trained in their use. Large sized cylinders should not be manually moved. When being moved, a cylinder should be firmly secured to the trolley in an upright position, the valve should be shut and any special fittings such as withdrawal equipment disconnected.
USE OF GAS CONTROL EQUIPMENT
When working with gas from cylinders or piped gas, it is important to use the correct pressure and flow control devices. Equipment should be manufactured from materials that are compatible with the gas, ensuring safety and purity. Installations handling oxygen should be free from flammable materials. Equipment used when handling flammable gases must be earthed, flameproof and free from potential sources of ignition.
Installations using very high purity ‘gases should be specially cleaned and incorporate a purge facility.
Flashback arresters should be fitted to all fuel gas lines and oxygen lines when they are used with fuel gases. These devices stop the flashback and prevent the potentially hazardous mixture of oxygen and fuel in the same hose. They may be fitted to shut off the flow of gas.
Precautions should be taken to avoid backflow of contaminants back to the cylinder. This may be overcome by the following means:
- Close the cylinder valve when not in use.
- Disconnect empty cylinders from the equipment in use.
- Fit a non-return or check valve.
- Fit an automatic shut off or isolation valve that is activated by low cylinder pressure.
Do not use a cylinder that has become contaminated.
Equipment used with gases should be in good working order and be regularly inspected for signs of leaks or damage. It should only be repaired by qualified persons.
Liquid gases and solid carbon dioxide present a number of hazards. Severe burns can result from mishandling, especially if the liquid is trapped in shoes or clothing. Gloves which cover the wrists and upper arms should be worn when decanting liquid nitrogen as trapped liquid can cause burns. When handling liquid gases use eye protection and approved containers which have handles.
The evaporation of large quantities of liquid nitrogen in confined areas (i.e. cold rooms) may result in displacement of oxygen and the risk of asphyxiation. Liquid nitrogen must not be transported in the passenger lift.
Keep the laboratory and benches tidy; store apparatus no longer required and ensure that waste materials are removed as soon as possible.
Keep all corridors and passages clear. In particular fire escapes and fire extinguishers access should not be impeded.
Be careful when opening laboratory doors. Except in dire emergency no one should ever run in a laboratory building.
Food and drink must not be taken into laboratories where flammable, poisonous or radioactive materials are to be used.
Make sure all containers are clearly labelled. Never take chances with an unlabelled container.
Australian standard AS 2211-1991 details safety precautions for the use of lasers. Lasers are grouped into five classes:
- Class 1 lasers are those that are intrinsically safe, that is, are safe by virtue of their engineering design.
- Class 2 lasers are low power devices which emit visible and invisible radiation and which may operate in either continuous wave (CW) or pulsed mode. There are also constraints on the power output or energy of Class 2 lasers, and these are described in the Standard. These lasers are not intrinsically safe, but eye protection is normally afforded by aversion responses including the blink reflex.
- Class 3A lasers emit higher levels of radiation than Class 2. Table III of the Standard describes the limits.
Direct inter-beam viewing of Class 3A with optical aids (for example, binocular telescopes) may be hazardous. For lasers emitting radiation in the range of 400 nm to 700nm, protection to the unaided eye is afforded by aversion responses including the blink reflex.
- Class 3B (Restricted) lasers operate at the same power levels as Class 3A but have higher levels of irradiance. Class 3B lasers may emit visible and/or invisible radiation at levels not exceeding the AEL’s specified in Table IV of the Standard. CW lasers may not exceed 0.5W and the radiance exposure from pulsed lasers must be less than 105 Jm -2. Direct inter-beam viewing near Class 3B lasers is always hazardous.
During any lifting, your back needs protection. Practising the correct technique during a lift means that when you have to make a heavy lift your back is already trained to be in the correct position. Bend your knees so that the load can be as near to the body as possible. This guarantees that the centre of gravity of the load is close to the spinal column. Then lift by straightening your knees, and with a straight back, rather than lifting with a straight back only.
If possible, avoid twisting or rotational movements while carrying a heavy load, as this also strains the back. In fact, avoid heavy loads wherever possible.
Material Safety Data Sheets
Material Safety Data Sheets ( MSDS) must be available and accessible for all hazardous chemicals which you use or store. These data sheets contain information about the physical properties of the chemical, First Aid measures, fire fighting measures, spill procedures, personal protection and toxicological data. MSDS’ are available from chemical suppliers or from the Chemistry Store (ext. 44027). A list of available MSDS data bases can be accessed from the School Safety Officer or using the link above.
Anyone intending to work with radiation emitting equipment should first consult with the Safety Officer about correct procedures. You will be required to be registered as a ‘radiation worker’ and wear a film badge.
Radiation workers who are expected to receive greater than 30% of the annual recommended effective dose limit of 20mSv should be subject to continuous personal monitoring.
For those workers whose annual dose is unlikely to exceed 30% of the effective dose limit, the Safety Officer in conjunction with the laboratory supervisor and the workers involved should assess individual monitoring requirements. Regular monitoring of the working environment may be sufficient in these circumstances.
The two main systems of personal monitoring that are routinely used throughout Australia are the photographic film badge and the thermoluminescence detector.
PHOTOGRAPHIC FILM BADGE
The photographic film badge operates on the principle that ionising radiation causes a latent image to be formed in the film emulsion. After processing, the degree of darkening produced depends on the amount of radiation to which the film has been exposed. Ionising radiation differs from light in that it is of higher energy and thus able to penetrate solid matter. For this reason the film badge holder contains a number of “filters” so that the type of radiation received can be determined and the amounts calculated.
THERMOLUMINESCENCE DETECTOR (TLD)
The thermoluminescence detector (TLD) utilises the ability of some materials to trap the electrons from ionising radiation. After irradiation, this material is heated, allowing the release of the trapped electrons and, in the process , the release of a photon of light. The release of light photons is proportional to the radiation dose the detector has received. this thermoluminescence material is usually impregnated into a small card of Teflon. the card is housed ion a holder similar to a film badge holder.
Film and TLD badges must be kept in good condition. Both badges are usually processed every three months, or more often if necessary. The results should be made available to the worker and are required by legislation to be kept by the School for a period of at least 50 years after the last entry.
The Safety Officer should maintain a cumulative record of film badge doses for all registered users.
Personal monitors are not transferable and should never be exchanged between individuals.
These badges may give inaccurate assessment if subjected to:
- pressure (finger nails, bending, ballpoint pens);
- wetting or laundering;
- exposure to extreme heat;
- some chemical vapours which can damage the card;
- storage near radioactive materials or X-ray equipment
Please refer to instrument manual and safety instructions before operating radiation emitting apparatus.

You will maintain an EHS information file that is accessible to all personnel in the work area. All EHS documentation relevant to the work area is to be located in this file. This includes hazard registers, environmental aspects registers, risk assessments, specified safe work procedures, work area training and authorisation records, and records of safety meetings/discussions and work area inspections.
Laboratory / Work Area Safety Training Document
You will develop a work area Safety Training Document that contains EHS information and the safety hazards and environmental aspects identified in the work area. It is your responsibility as a supervisor to ensure that all work area personnel are adequately inducted and trained before they undertake hazardous tasks or use equipment, and that training is on-going and managed. Your ‘authorisation’ procedure should be auditable by checking log books, diaries etc. or by interviewing workers.
Training Needs Assessment
You will complete and file a Training Needs Assessment for all personnel in your work area on an annual basis, and ensure that the training is provided and documented.
Details of training provided by The University can be found in Themis
You will hold regular work area safety meetings to discuss EHS matters and appraise personnel of any changes or additions to EHS procedures.
Work Area Safety Inspections
You will conduct and document quarterly EHS inspections of the work area (six-monthly for office areas) using the checklist downloaded from the website, and provide evidence that ‘actions’ identified have been followed through. You will seek input from all people in your area during the inspection process; after all, it is their safety you are managing.
Safety Hazard Register, Risk assessments, Risk Control Measures
You will ensure that your work area has an up to date Safety Hazard Register identifying all hazardous procedures and equipment, and that formal risk assessments are completed and filed for all significant hazards (identified as medium or high risk). Risk control measures must be devised and implemented for all identified hazards (generally outlined in your Safety Training Document). A written work procedure must be developed for all significant hazards.
Environmental Aspects Register, Risk assessments, Risk Control Measures
You will ensure that your work area has an Environmental Aspects Register (with date and review date) identifying procedures with an environmental impact, and that formal risk assessments are completed and filed for all significant aspects (identified as medium or high risk). Risk control measures must be devised and implemented for all identified aspects (generally outlined in your Safety Training Document). A written work procedure must be developed for all significant aspects.
Plant Register, Plant Risk Assessments
Some equipment is identified as ‘Plant’ because of government regulations. A register of Plant in the work area must be maintained together with plant risk assessments, risk control measures and work procedures.
Manual Handling Assessments
You will ensure that Manual Handling Risk Assessments are completed (by appropriately trained people) and filed for all identified manual handling tasks in your work area, and that risk control measures are incorporated into work procedures.
Field Work Assessments
You will ensure that Field Work risk assessments are completed and filed for all off-campus work, and that itineraries and records are filed in your work area. It should be possible to cross-check the vehicle log books against these records.
You will ensure that your work area has an inventory of Chemicals stored in the work area. Material Safety Data Sheets (MSDSs) for all hazardous chemicals used in the work area must be readily accessible.
Procedures for Selection, Use and Maintenance of Personal Protective Equipment
If your work procedures include the use of Personal Protective Equipment (PPE) you must maintain records to show that it is appropriate for the purpose, that it is used and maintained appropriately, and that users are properly trained.
You will ensure that casual visitors to the work area are appropriately trained / escorted and are aware of all relevant hazards.
You will ensure that appropriate measures are in place in the work area to safeguard the entry of unsupervised personnel. This includes the provision of security measures and/or appropriate warning signage.
- SUITABLE CLOTHING must be worn. Long trousers are recommended
- PROTECTIVE CLOTHING must be worn in chemical handling areas for protection in case of chemical spill.
- SOUND FOOTWEAR must be worn. Thongs, sandals, clogs, scuffs and other open-style shoes are not recommended.
- SAFETY GLASSES should be worn when handling acids, cryogenics and solvents. Glasses must conform to Australian Standard 1337.
- PROTECTIVE GLOVES of a suitable type must be worn when handling chemicals, oils and cryogenic liquids.
- LONG HAIR must be safely tied back.
All water connections should be made secure using appropriate vinyl tubing. For experiments of long duration stainless steel clips should also be used.
Remember that at the end of the day water pressure may rise sharply and that all water lines must be sound and properly secured. Flooding can cause very extensive damage in the building.
Withdrawal of Equipment or Services
In the event of a malfunction in services or equipment withdraw the item from usage. If assessed as unsafe a ‘TAG’ will be attached to the item or service which indicates that it is unsafe to use until repairs have been carried out. Notify the workshops, maintenance or the Safety Officer immediately. TAG’s are available from the workshops or the Safety Officer.
If equipment is found to be unsafe and there is risk to yourself or others as a result of its use, the equipment must be isolated from the power supply and a ‘TAG’ must be placed on the item to ensure that others are aware of the hazard. This equipment should be inspected by a qualified person as soon as possible. If the standard TAG is not available then a label stating the type of fault, date it was tagged and signed by the operator must be attached. This must be recorded as soon as possible on the workshop repair request form.
Reference Faculty of Science Safe Work Procedures Section 1.27 Tagging of Unserviceable Equipment.
Work Area Safety and Environment Inspections
Regular inspections of laboratories and work areas for compliance with safety and environmental criteria are an important part of the Schoolof Physics Environment and Safety Program. The environment / safety inspection checklist is designed to aid workers in identifying areas that need attention.
Quarterly Work Area Environment and Safety Inspections: Procedure
- The dates of quarterly inspection deadlines are specified in the School of Physics Environment and Safety Manual / Website
- The Chairman of the Safety and Building Committee will e-mail all Work Area Supervisors two weeks in advance of the inspection deadline requesting them to hold a work area safety meeting, collectively fill out the inspection checklist, and file it in the work area safety folder.
- The Safety Officer will ensure all work area records are checked one week after the inspection deadline to ensure inspection has been completed and documented
- The School of Physics Safety and Building Committee will report to the Head of Department (via Departmental Committee) on compliance
Offices in Work Areas are inspected six-monthly. Deadlines are specified in the
Work Area Environment and Safety Inspection Checklist and Meeting: Procedure
- The Work Area Supervisor convenes a meeting of all available work area personnel prior to the inspection deadline
- Complete the Work Area Environment and Safety Inspection checklist
- Record details of any non-conformance or matters requiring action in the Actions Table on the checklist
- Determine what corrective actions are required, designate someone to be responsible for ensuring actions are completed, and set a date for completion
(If any corrective action requires expertise or resources not available in the work area, it must be reported in writing to the Departmental Safety Officer for resolution)
- Ensure that all corrective actions from the previous work area inspection are completed, or note progress on actions still outstanding
- Discuss other relevant Environment, Health and Safety issues
- File completed Checklist and any records/notes of other matters discussed in the Work Area Environment and Safety Folder
- Notify Work Area personnel in writing of any changes to policy or procedures

Working Outside “Normal” Working Hours
All staff and students, with a demonstrated need to work outside normal working hours, MUST obtain permission from the Head of the School or from nominated Group Leaders. Research workers should try as far as possible to organise their experimental work so that hazardous operations are carried out WITHIN NORMAL WORKING HOURS. When such operations have to be performed outside normal working hours, the operator must first make sure that a SECOND PERSON is available within the IMMEDIATE VICINITY throughout the experiment, so as to give help, if needed. HAZARDOUS OPERATIONS, i.e. high voltage equipment, toxic chemicals, should NOT be performed outside normal working hours (see above). It is inadvisable to work alone with any hazardous material or machinery and every effort must be made to ensure that some one is working within calling distance should an emergency arise.
All persons working in the School between the weekday hours of 6.30 pm and 8:00 am and on weekends must sign an “OUT-OF-HOURS” REGISTER, located at the Reception Desk, ground floor. This register will be used by emergency services to account for personnel working outside normal hours, should the need arise. It will also assist night security patrol officers.
For many years there have been regulations, standards and codes of practice specifying minimum requirements for the design, manufacture, and use of machines and lifting gear. These regulations appear to have been successful in reducing the number of accidents caused by equipment failure.
Your eyes are very important to you-protect them. Always wear suitable glasses, goggles or a shield when you are exposed to risk of eye injury. If a foreign body lodges in your eye, seek proper first-aid attention. Do not allow your fellow employee to remove it. All welding operations should be properly screened, as electric and gas welding’ can cause damage to your eyes under certain conditions. If chemicals come into contact with your eyes, immediately apply plenty of clean water and obtain skilled attention as soon as possible.
In areas where the noise exceeds a given level, ear muffs must be worn.
Do not use or tamper with electrical equipment unless you are properly authorised to do so. Electrical equipment must at all times be considered to be ‘live’, and therefore dangerous. Report and label any apparent defects in wiring or electrical equipment. Do not leave extension cords on the floor when not in use: coil them up and place them in storage, preferably lying flat, not hanging on a hook.
Observe these points in regard to clothing, personal cleanliness and appearance.
- Wear overalls all the time at work. They should be cleaned regularly and must fit comfortably.
- Loose, ill fitting and torn clothing can become entangled in machinery and should not be worn.
- Suitable footwear is essential. Safety boots or shoes fitted with steel toecaps are recommended.
- Long hair is dangerous. Factory regulations demand that a hair net be worn to cover long hair.
- Preferably, for safety in the workshop, hair should be worn short.
- Where there is any danger of objects falling from above or a risk of bumping your head on
- sharp metal corners, wear a safety helmet.
- Where a workshop has been allowed to become dirty and untidy, general inefficiency, poor work practice and frequent accidents often result.
- Remember, workshop cleanliness is a function of both management and staff, for the benefit of both. Fundamentally, then, tradespeople make their own working conditions by the attitude they adopt.
- The efficient operation of any workshop will depend largely on the planning and foresight devoted to its design and construction. Important features to be considered are:
- the most suitable layout for maximum production and efficiency;
- measures that will ensure the safety of the operator, machine and the environment; adequate provision for the maintenance of tools and equipment.
