Chemicals can impact the tegument by contact or they affect the organic structure either through the digestive system or via the lungs if air is contaminated with chemicals. vapour. mist or dust. There can be an acute consequence. i. e. the individual is affected instantly. or there can be a chronic consequence. i. e. the individual is affected in the medium to long term due to the accretion of chemical or substances in or on the organic structure. Introduction

and “management controls” for guaranting that these are implemented and remain active. THIS IS AN IMPORTANT PRINCIPLE TO REMEMBER.

The execution of controls to repair a specific jeopardy. e. g. ironss to forestall gas cylinders tumbling over. or hearing defenders to cut down exposure to resound. must be supplemented by direction activities to guarantee they are being implemented. that they are equal. and that they remain effectual.

The mechanism for the control of a jeopardy may non needfully be a physical one. but may be a regulation or pattern designed to cut down the hazard from the jeopardy. It is necessary to guarantee that one time jeopardy controls are put in topographic point they stay in topographic point and are used. and it is besides necessary to supply a feedback mechanism for guaranting whether or non the controls are equal and duties are Understood by all.

Control OPTIONSWhen a jeopardy has been identified and assessed as necessitating some control step. so the following procedure to travel through is the choice of which option is required. The concluding pick of an option is based on factors such as the possible badness of injury posed by the jeopardy. the likeliness of hurt or unwellness occurring. the cost of control steps. or whether it has been identified as a important jeopardy.

It is of import. nevertheless. to Look AT ALL OPTIONS before doing a determination. even though the identified jeopardy may already hold some controls in topographic point. CONTROL OF SIGNIFICANT HAZARDSHazards that are assessed as “significant” nowadays such a grade of hazard that the Act requires a more formal attack in covering with them. The primary purpose is the riddance of important jeopardies if operable. Sections 8. 9 and 10 of the Health and Safety in Employment Act 1992 contain specific demands for the control of important jeopardies. These subdivisions require that the undermentioned stairss are to taken one time important jeopardies have been identified in an organisation:

1. Significant jeopardies to employees are to be eliminated where operable. 2. If this is infeasible. those jeopardies are to be isolated. 3. If this is besides infeasible. all operable stairss must be taken to minimise the likeliness that the jeopardy will be a beginning of injury to the employees. If this measure is followed:

• It must include the supply and usage of protective equipment ; and• Employee exposure to the jeopardy must be monitored. and wellness monitoring carried out with employee consent.Once the important jeopardies in the workplace have been identified. it is necessary to make up one’s mind which of the three stairss is to be used to command each jeopardy. Outline of the procedureFor each of the antecedently identified important jeopardies the undermentioned inquiries must be asked in order:• Can the jeopardy be eliminated?If so. name the stairss to accomplish this or. if non. why non?Test YOUR REASONS FOR NOT ELIMINATING IT AGAINST THE “ALLPRACTICABLE STEPS” REQUIREMENTS.OR IF NOT. THEN• Can the jeopardy be isolated from the employees?If so. what stairss are needed or. if non. so why non?Test YOUR REASONS FOR NOT ISOLATING IT AGAINST THE “ALLPRACTICABLE STEPS” REQUIREMENTS.OR IF NOT. THEN• What will be done to minimise the likeliness of injury from the jeopardy? • What equipment and vesture are needed to protect employees from the injury?• How are employees’ exposure to the jeopardy and their wellness in relation to the exposure being monitored?List the replies and soTest YOUR STEPS FOR MINIMISING THE LIKELIHOOD THAT THEHAZARD WILL CAUSE HARM AGAINST THE “ALL PRACTICABLESTEPS” REQUIREMENTSThe hierarchy of stairss above ensures that providing employees with protective equipment to guard against the jeopardy is non done without first sing and measuring the other more effectual options.

CONTROL OF OTHER HAZARDSThe procedure used for important jeopardies may besides be used to find the control methods for other jeopardies. However. should you take non to. so the following procedure can be used.The procedure outlinedFor each “other hazard” ask these inquiries in the undermentioned order: • Can the jeopardy be removed by design and technology?• Can the jeopardy be removed by permutation?• Can the hazard from the jeopardy be reduced by altering the procedure? • Can the hazard from the jeopardy be reduced by enveloping it to insulate it from workers?• Can the jeopardies be removed at beginning before they can impact the work force? • Can the jeopardy be reduced by segregating the procedure from workers other than those needed to the procedure?• Can personal protective equipment be used to cut down the hazard of hurt? • Can regulations or processs be developed to cut down the hazard of hurt? Put in topographic point and how you intend to implement these jeopardies. It is of import to recognize that the methods and systems for the control of jeopardies. whether important or non. Make NOT be in isolation from the other activities organisations undertake in order to transport out their concern. The hazard designation and control Risk Assessment Stairss: –

* Step 1 – Identify the Hazards* Step 2 – Decide Who Might be Affected* Step 3 – Ensure Necessary Controls are Adequate and In Topographic point* Step 4 – Record the Findingss* Step 5 – Review What you Have Done

A hazard appraisal should follow five simple stairss:

Identify the HazardsMeasure 1 – Look for the jeopardies. If you are making the appraisal yourself. walk around your workplace and expression at what could moderately be expected to do injury. Ignore fiddling points and concentrate on what could ensue in serious injury or affect several people or more. Try to look at your concern with a fresh brace of eyes.

Decide Who Might be AffectedMeasure 2 – Decide who might be harmed and how. Remember that some people may be at greater hazard. for illustration trainees. new members of staff. contractors. immature people. anticipant female parents or employees with bing medical conditions. Besides do non bury to include cleaners. visitants. care people. members of the populace particularly kids. and shift workers.

Ensure Necessary Controls are Adequate and In Topographic pointMeasure 3 – Evaluate the hazards and make up one’s mind whether bing safeguards are equal or whether more demands to be done. See how likely it is that each jeopardy could do injury. Even after all safeguards have been taken. some hazard normally remains. What you have to make is to make up one’s mind for each important jeopardy is whether this staying hazard is high. medium or low. First. inquire yourself: * Have you done everything you are lawfully required to make? For illustration. there are legal demands on bar of entree to unsafe parts of machinery. * Have you applied by and large accepted industry criterions? The purpose is to do all hazards little. If you find something that requires action. inquire yourself: * Can I acquire rid of the jeopardy wholly?

* If non. how can I command the hazard so that injury is improbable? Use the undermentioned hierarchy to cut down hazard:* Try a less hazardous option* Prevent entree to the jeopardy* Form the work activity to cut down exposure to the jeopardy * Issue Personal Protective Equipment ( PPE )* Provide lavation installations for the remotion of taint and first assistance

Record the FindingssMeasure 4 – Record your findings. If you have five or more employees. you must enter the important findings of your hazard appraisal. This means composing down the important jeopardies you have identified and what action you have taken to cut down the hazard. There is a legal demand to do certain that your hazard appraisal is suited and sufficient. You will necessitate to demo that: * Proper cheques were made

* You identified who might be harmed. and how* You dealt with all the obvious or important jeopardies* The action you took was sensible and reduced the hazard

Review What you Have DoneMeasure 5 – Review your appraisal. A hazard appraisal should be a on the job papers that is reviewed on a regular basis to guarantee that it is still effectual. You should see reexamining your appraisal. for illustration. when your chief concern activity alterations. if you move premises or when you purchase new pieces of equipment. If. when reexamining your appraisal. you identify new jeopardies so your appraisal may necessitate to be revised to command these new jeopardies. Functions and Duties

1. Designate. assign. appoint or prosecute a competent individual taking a squad of forces ( including contractors ) associated with the procedure or activity to carry on hazard appraisals ; 2. Ensure that the hazard control steps are implemented without undue hold after the completion of hazard appraisal ; 3. Inform all individuals working at the workplace of the hazards. and the agencies to understate or. where possible. extinguish the hazards ; 4. Supply a hazard appraisal registry to enter the findings of hazard appraisal ; 5. Endorse and O.K. the hazard appraisals conducted ;

6. Keep hazard appraisal records for review for at least three old ages from the day of the month of the appraisal ; and subject the records to the Commissioner for Workplace Safety and Health if the Commissioner so requires ; 7. Review and update the hazard appraisal at least one time every three old ages or whenever there is a important alteration in the work. or after an incident affecting the work procedure ; 8. Ensure that all employees are cognizant of the hazard appraisal for the work activity they carry out ; 9. Develop and implement safe work processs ( SWPs ) for work which poses safety or wellness hazards to workers ; and 10. Keep a written description of SWPs and bring forth this to the inspector for review when requested.

MANAGEMENT CONTROLSThese are the activities that an organisation uses to pull off a safety and wellness programmed. There are normally a figure of basic direction control activities that are common to all jeopardies. although some jeopardies may necessitate more. These include:

• Involvement of employees in the development of wellness and safety processs.• An information system to guarantee employees are informed about and understand the hazards from jeopardies they work with.• An accident coverage and probe system.• Regular studies of the workplace.• Responsibilities being assigned to guarantee jeopardy controls are implemented and remain effectual.• An audit system for look intoing that the controls for specific jeopardies are in topographic point and working.• An equal preparation programme and equal supervising for all staff.• Implementing exigency processs. possibly in concurrence with local exigency services. to restrict the effects of an exigency. Duty

Duties are assigned to guarantee that the being of each jeopardy is made known to all those exposed to it. and that they are instructed in the usage of the correct procedures when exposed to the jeopardy.

ExampleAn illustration of the connexion between the direction control activities mentioned above and the local control activities can be made by looking at the following simple illustration. where the jeopardy could non be eliminated or isolated. Hazard: Exposure to talc when emptying bag into hopper.

Appraisal: Sustained inspiration of important sums of talc can bring forth diagnostic pneumonoconiosis. MSDS sheetsupplied with merchandise provinces safeguards needed.Local controls: – Ventilation goon over hopper ( interlocked with procedure ) .– Protective face mask ( worn when emptying bags ) .– Disposable overalls.Management controls:– Plant study every month to look into processs and the efficiency of airing system.– Training for staff in jeopardies of talc and grounds for protective vesture.– Audit every twelvemonth to guarantee preparation is given and that jeopardies and duties are known about and understood.Medical scrutiny of people utilizing talc every three old ages as portion of ongoing monitoring procedure.– Test every six months to what extent staff are exposed to talc. Use personal monitoring method.– Employees given the consequences of monitoringHazard Control PlanTo be developed in audience with direction and employees with specialist advice as appropriate.HAZARD TO BE CONTROLLEDA.

10 Types of jeopardies

Use these notes to assist you place and measure jeopardies that might happen in your workplace.

Chemical jeopardiesChemicals can impact the tegument by contact or the organic structure either through the digestive system or through the lungs if air is contaminated with chemicals. vapor. mist or dust. There can be an ague ( immediate ) consequence. or a chronic ( medium to long-run ) consequence from the accretion of chemicals or substances in or on the organic structure.

Noise jeopardiesExcessive noise can interrupt concentration. interfere with communicating. and consequence in loss of hearing. High impact noises are peculiarly detrimental. Noise can besides dissemble out signals. impacting communicating or danger warnings.

Radiation jeopardiesEquipment such as radioactive gauging devices or the radioactive hint component used in analytical chemical science produce Ionizing radiation. Non-ionizing radiation screens infrared radiation ( heat-producing procedures ) . optical masers. UV radiation ( welding. sunshine ) . and microwaves ( high-frequency welders. freezing drying ) .

Electrical jeopardiesThese include the hazard of hurt from all signifiers of electrical energy.

Lighting jeopardiesInadequate lighting degrees are a possible safety jeopardy. A common job country is the reaction clip needed for the eyes to set from a brilliantly lit to a darker environment — such as a forklift driver coming indoors from bright sunshine. Impermanent lighting is frequently unequal.

Vibration jeopardiesThis includes whole-body quiver — for illustration. truck drivers. people standing on vibrating platforms. and operators of nomadic equipment — and besides more localised quiver effects from such equipment as manus tools. chain saw. and pneumatic cocks.

Temperature jeopardiesExtremes of cold or heat can do jobs such as fatigue. exposure to infections or reduced capacity to work.

Biological jeopardiesThese include insects. bacteriums. Fungis. workss. worms. animate beings and viruses. For illustration. domestic fowl workers exposed to bird plumes and dungs to which they are allergic can contract a medical status. Brucellosis is a good known job in New Zealand associated with people managing meat and meat merchandises infected with German measles. Hepatitis and the AIDS virus are other biological jeopardies.

Ergonomic jeopardiesBiotechnologies ( the ‘fit’ between people and their work ) covers hazard of hurt from manual handling processs. falsely designed desks or workstations. sound and ocular dismaies. and color coding control mechanisms.

Physical jeopardiesThese include a broad scope of hurt risks— every bit diverse as being caught in or by machinery. buried in trenches or hurt by fall ining machinery. This class besides includes the jeopardies from working in confined infinites. being hit by winging objects. caught in detonations. falling from highs and stumbling on obstructions. HIERARCHY OF HAZARD CONTROLS

1. Elimination Most Effective Control

2. Substitution

3. Technology Controls ( Safeguarding Technology )

4. Administrative Controls ( Training and Procedures )5. Personal Protective Equipment Least Effective Control

Examples OF EACH STEP IN THE HIERARCHY OF HAZARD CONTROLS1. EliminationThe best manner to command a jeopardy is to extinguish it and take the danger. This can be done by altering a work procedure in a manner that will acquire rid of a jeopardy ; replacing anon-toxic chemical for a toxic substance ; holding workers perform undertakings at land degree instead than working at highs ; and other methods that remove the jeopardy all together.

2. SubstitutionThe 2nd best manner to command a jeopardy is to replace something else in its topographic point that would be non-hazardous or less risky to workers. For illustration. a non-toxic ( or less toxic ) chemical could be substituted for a risky one.

3. Technology Controls ( Safeguarding Technology )If a jeopardy can non be eliminated or a safer replacement can non be found. the following best attack is to utilize technology controls to maintain the jeopardy from making the worker. This could include methods such as utilizing noise stifling engineering to cut down noise degrees ; enveloping a chemical procedure in a Plexiglas “glove box” ; utilizing mechanical lifting devices ; or utilizing local fumes airing that captures and carries away the contaminations before they can acquire in the take a breathing zone of workers.

4. Administrative Controls ( Training and Procedures )If technology controls can non be implemented. or can non be implemented right off. administrative controls should be considered. Administrative controls involve alterations in workplace policies and processs. They can include such things as: * Warning dismaies

* Labeling systems* Reducing the clip workers are exposed to a jeopardy. and* Training.

For illustration. workers could be rotated in and out of a hot country instead than holding to pass eight hours per twenty-four hours in the heat. Back-up dismaies on trucks that are endorsing up are an illustration of effectual warning systems. However. warning marks used alternatively of rectifying a jeopardy that can and should be corrected are non acceptable signifiers of jeopardy control.

5. Personal Protective EquipmentThe usage of personal protective equipment ( PPE ) is a manner of commanding jeopardies by puting protective equipment straight on workers’ organic structures. Examples of personal protective equipment include: inhalators. baseball mitts. protective vesture. difficult chapeaus. goggles. and ear stoppers.

Personal protective equipment is the least effectual method for protecting workers from jeopardies. PPE should be used merely while other more effectual controls are being developed or installed. or if there are no other more effectual ways to command the jeopardy.

This is because:* The jeopardy is non eliminated or changed.* If the equipment is unequal or fails. the worker is non protected. * No personal protective equipment is fool-proof ( for illustration. inhalators leak ) . * Personal protective equipment is frequently uncomfortable and can put an extra physical load on a worker. * Personal protective equipment can really make jeopardies. For illustration. the usage of inhalators for long periods of clip can set a strain on the bosom and lungs. While there are some occupations. such as taking asbestos. where have oning equal personal protective equipment is perfectly indispensable. there are many occupations where employers manus out personal protective equipment when in fact they should be utilizing more effectual jeopardy control methods.


When be aftering for jeopardy controls. retrieve that the control selected must non extinguish one jeopardy while making another.

For illustration. it is non acceptable to take air contaminations from one country by venting them to another country where another group of workers will be exposed. Hazard control steps should extinguish or cut down jeopardies for all who are potentially exposed to them.


The ability and duty to plan occupations safely in the first topographic point. or redesign them when a jeopardy is detected. lies with direction. It is the function of workers and brotherhoods to advance the usage of the “Hierarchy of Controls” . doing certain those employers are supplying the most effectual methods for jeopardy control possible.

Chemical jeopardiesA chemical jeopardy can be considered as any chemical agent that may compromise H2O safety or suitableness. as shown in Table 5. 1.Table 5. 1: Examples of chemical jeopardies that may happen in drinking-water supply systems. Chemicals from watershed/catchment| Chemicals fromReservoir storage| Chemicals fromWater intervention process| Chemicals from distribution | | | | |

Nitrate Arsenic Fluoride PesticidesOther heavy metalsOrganic poisons Herbicides Rodenticides| Algal toxins Cleaners Liner chemicals LubricantsPesticides Herbicides| Flocculants pH adjustors Disinfection byproductsImpurities in treatmentchemicals| Copper Lead Cleaners PetroleumproductsLiner chemicals|

The control measures ( see Chapter 6 ) needed and the frequence of monitoring should reflect the likeliness and effects of loss of control. In any system. there may be really many jeopardies and potentially a big figure of control steps. It is hence of import to rank the jeopardies in order to set up precedences. Simple hazard appraisal matrices are available and have been successfully applied toprioritising jeopardies in the H2O industry ( e. g. Gray and Morain 2000 ; Deere et al. 2001 ) . These typically apply proficient information from guidelines. scientific literature and industry pattern with good informed adept opinion supported by third-party equal reappraisal or comparing against other systems ( benchmarking ) . Benchmarking differs from other quality betterment techniques in that its focal point is on placing what the external best patterns are for cardinal concern maps and procedures and has been defined as:

“A method for easing uninterrupted betterment by consistently comparing one’s ain procedures. patterns and public presentation against the best pattern of others with a position to following. accommodating or heightening that pattern to one’s ain situation”
