How accidents happen

• Lack of care• Did not use common sense/stupidity• Unsafe acts• Unsafe conditions• Acts of God • Lack of supervision/ poor training• Faulty equipment

6

Safety in the workplace is everyone’s responsibility

No one persons obligations in the workplace outweigh, or supersede another person’s obligations.

7

Australian health and safety law is governed by• A framework of Acts• Regulations• Supporting Codes of Practice &• Standards

8

Monitoring safety and maintaining a safe environment requires

The correct Implementation of

• Risk Identification• Risk Assessment• Risk Control

9

Risk and hazards

• Hazards can cause injury, disease, economic loss or environmental damage

• Risk - possibility that something will occur; expressed in terms of probability

• Risk assessment uses data, hypothesis and models to estimate probability of harm due to exposure to hazards

10

Major types of hazards

Major workplace hazards may include:• Manual handling• Chemical or hazardous substances• Occupational Overuse Syndrome • Noise• Physical worksite or environmental problems• Equipment and machinery

11

Hazard Identification Steps

• Job Safety Checks• Employee Consultation• Safety Audits

12

Manual handling hazards

Annual handling hazards may be caused by actions related to:• Push• Pull• Lowering• Lifting• Carrying

13

Chemical and hazardous substances

• Toxic chemicals - each has specific median lethal dose

• Chemicals, radiation or viruses• Hazardous chemical harm by:

• Flammable or explosive• Irritation of damaging tissue• Interfering with respiration• Causing allergic reactions

14

Chemical and hazardous substances

Impact cause by• Inhalation• Ingestion• Skin or eye contact

Harm can be on:• Person (Tumors, burns, etc.)• Future generations (genes & embryos)• Environmental and lifestyle factors

15

Physical hazards

Commonly involves worksite layout, structure and equipment

Can extend beyond worksite to • Earthquakes - fracture or shift in earth’s crust deformation• Volcanoes• Floods• Storms

16

S.A.F.E. process to remove workplace hazards

Spot the hazard.

Assess the risk.

Fix the problem.

Evaluate results. 

17

Addressing external physical hazards

Reducing external physical hazards requires engineering and planning:• Examine historical records and make geological

measurements and weather forecasts• Map high-risk areas• Building codes regulate design and placement of

buildings• Predict possible earthquakes and natural events

18

Biological hazards

Non-transmissible diseases are not caused by living organisms; cannot spread

Transmissible diseases are caused by infectious agents (pathogens) and spread by vectors; agents include:• bacteria• virus• protozoa• parasites

19

Biological hazards

Seven deadliest infectious diseases• Acute respiratory infections• HIV/AIDS• Diarrheal diseases• Malaria• Tuberculosis• Measles• Hepatitis B

20

Assessing the risk

Assessing risk involves considering these factors … • How likely it is that an accident will occur• If an accident occurs, how severe would the

consequences be

21

Risk analysis

• Identify hazards and evaluate associated risks• Rank risks• Determine options and make decisions about

reducing or eliminating risks• Inform decision makers and public about risks

22

Risk assessment

• Determine types of hazards involved• Estimate probability that each hazard will occur• Estimate how many people are likely to be

exposed to and suffer serious harm from each hazard

• Statistical probabilities and forecasts

23

Comparative risk analysis

• Staff and management perceptions of greatest risks may differ

• Communication needs to be clear and use common language

• Risk-benefit analysis – estimates must cover both risks and benefits

• Immediate needs should not outweigh long-term planning

24

Risk control involves

Modifying the design of the workplace by• Design or Substitution• Engineering Controls• Administration• Training Personnel• Personal Protective Equipment

25

Hierarchy of risk control

Substitute/ Change(Change and replace)

Eliminate(Remove, phase out,

redesign))

Engineer Controls(Renew workplace/ context)

Administrative Controls(Change work, set

maintenance new schedule, new procedures,

signage, etc.)Protective Controls

(Protectiveequipment,

clothes)

26

Workplace safety inspections

• Continuous - Ongoing inspection conducted by employees as part of their job.

• Periodic - Inspections scheduled to be made a regular intervals• Intermittent - Inspections made at irregular intervals. • General – inspection of places which do not receive periodic

inspections

27

Points to consider when conducting inspections

• Planning and preparation is critical• Who will carryout the inspection• What needs to be inspected• How often must items be inspected
