TASK 3: Occupational Health and Safety Management System (OHSMS)/ AS 4801:2001. Complete the following tasks using the example of a construction company in Australia or elsewhere.

3.1: Determine the legislative requirements for the company’s operations (federal and state legislations) that are required by the AS 4801 (one page).

Safe Removal of Asbestos (NOHSC: 2002)

Code of Practice for the Management and Control of Asbestos in the Workplace (NOHSC: 2018)

Adopted National Exposure Standards for Atmospheric Contaminants in the Occupational Environment (NOHSC : 1003)

Guidelines for Integrating OHS into National Industry Training Packages

National Standard for Construction Work (NOHSC 1016)

Prevention of Falls in General Construction

National Code of Practice for the Control of Workplace Hazardous Substances (NOHSC: 2007)

Workplace Injury and Disease Recording Standard in the Workplace

National Standard for the Control of Major Hazard Facilities (NOHSC 1014)

National Standard for Manual Tasks

National Standard for Occupational Noise (NOHSC: 1007)

Guidance on the Principles of Safe Design for Work

3.2: Describe at least 10 risks for company’s operations in accordance with the AS/NZS 4801 (one page).

1. Falls from heights – These usually happen when guardrails, harnesses and safety net systems are not in place.

2. Musculoskeletal disorders – In construction these may manifest after repetitive strain injuries, cumulative trauma disorders, segmental vibration (hand-arm vibration) or others. This accounts for 1/3 of all reported serious workplace injuries

3. Exposure to hazardous chemicals – These are commonly caused by wrongful or erroneous communication of the hazards the chemicals in the area can cause

4. Occupational lung disease – These may be caused by insufficient oxygen conditions, harmful dusts, smokes, mists, fogs, vapors and sprays.

5. Unexpected start-up of machinery or equipment – These occur when equipment or machinery have not been properly locked out or tagged out, causing injury to the employee.

6. Electrocution – This happens when the human body comes in contact with a bare conductor and electricity flows through the body.

7. Occupational hearing loss – These may be caused by explosions and thermal injuries (such as slag burns sustained when a piece of welder’s slag penetrates the eardrum, or continuous exposure to noise in excess of 85 decibels.

8. Power tool accidents – These involve the potential hazards presented by the equipment’s moving parts involving rotary movements (power saw), nip points (blades or staples), or tool projections (electric drills)

9. Excavation Accidents –

10. Motor Vehicle Accidents – These major safety hazards risk the health and safety of the worker as well as that of the equipment, both of which are considered vital and economically essential to construction

3.3: Develop a risk assessment chart and assess all the risks identified under 3.2 (one page).

3.4: Describe at least 2 actions for all the risks identified under 3.2 (one page).

RISK ACTIONS

 Falls

1. Fall protection at six feet from the lower level must be implemented.

2. Fall protection can be ensured by guardrail systems, safety net systems,

positioning device systems and warning line systems.

Musculoskeletal

disorders

1. Implement an Ergonomics Program to prevent work-related musculoskeletal

disorders.

2. Training and matching the proper worker to the task.

 Exposure to Hazardous

Chemicals

1. Proper labelling of chemicals and the potential hazards these cause must be

properly placed.

2. Assigned personnel must wear protective clothing, masks and gloves as such

required before handling these chemicals.

 Occupational lung

disease

1. Masks must be worn during work times in dusty areas; removing dust from

source and practice good occupational hygiene.

2. Exposure to smoke, fumes and other respiratory irritants must be minimized

 Unexpected start-up of

machinery or equipment

1. Shut down the machine or equipment  and isolate it from its energy source

2. Lockout-tag out practices must be performed.

 Electrocution

1. Proper installation of electrical circuit, insulation, grounding and fuse or circuit

breaker.

2. Constant maintenance and monitoring of electrical equipment and wiring can

prevent electrocution accidents

Occupational hearing

loss

1. The use of hearing protection devices such as ear plugs, canal caps or ear muffs

can reduce noise and prevent hearing problems or loss in employees.

2. Procedures that creates a lot of noise must be performed when there is least

discomfort to the immediate and surrounding areas (example no drilling at night

time)

 Power tool accidents

1. Training on the proper handling of power tools should be done

2. Safety guarding devices, protective clothing and gear must be used or worn

during the use of power tools.

 Excavation accidents

1. Application of fall control measures.

2. Backfilling the excavation as work progresses

 Motor vehicle accidents

1. Motor vehicles must have an emergency brake system, service brake system and

a parking brake system.

2. All vehicles must have an audible warning system if the operator decides to use

it.
