Q

What is the accident cost iceberg?

A

Top of the iceberg is the medicinal compensation costs for individual
Lower of the iceberg is the ledger costs, property damage, uninsured miscellaneous costs
Showing us the top of iceberg is the direct cost while lower of the iceberg is the indirect causes of accident

Q

What is occupational hygiene?

A

Art and science dedicated to anticipation, recognition, evaluation, control of environmental stressors arising in the workplace that can result in injury, illness, impairment or affect the well being of workers and members of the community

Q

What are the correlations to health/hygiene with safety?

A

Something not safe, accident occur
Leads to death or injury, and this is short term
If hazardous to health, leads to disease or physiological impairment. Leads to some form of illness/long term
Important to create healthy and safe work environment

Q

What are physical hazards?

A

Noise, vibration, radiation

19
Q

What are psychosocial hazards?

A

Worker morale, stress, violence, harassment

20
Q

What are safety hazards?

A

Hazards likely to cause injuries
Common in every workplace, should be avoided because they result in considerable amount of lost time-injuries

21
Q

What are ergonomic hazards?

A

“Human factors”
Workplace conditions posing risk of injury to musculoskeletal system of worker
Matching the job to the worker and product to user
Design workplace for worker, not other way around

22
Q

What are Chemical hazards?

A

Solid, liquid, gases
State of chemical dictates how and where it will travel, and how it enters the body

23
Q

What are biological hazards?

A

Usually in agricultural, research labs, hospitals
Microbiological agents
Infectious agents
Cause allergic reactions

24
Q

What are physical hazards?

A

Source of energy causing injury or disease
Noise is ubiquitous and excessive noise leads to noise-inducing hearing loss
Thermal stress when workplace is hot/cold
Vibration leads to vibration-induced white fingers
Radiation can lead to cancer

25
Q

What are psychosocial hazards?

A

Affect workers psychological response to workplace, causes form of stress

26
Q

What are exposure risk factors?

A

Hazard only dangerous if exposed to, have to know the exposure risk factors

27
Q

What are the exposure risk factors?

A

Nature of hazard
Intensity of exposure
External factors which may influence hazard
Route of entry
Effects of exposure

28
Q

What is the nature of hazard?

A

Degree of toxicity
Chemical characteristics- alkaline/acid/neutral
Physical characteristics - state of the agent

29
Q

What is the intensity of exposure?

A

Concentration—> concentrated form can hurt
Duration of exposure —> entire work shift, how long
Frequency of exposure —> everyday, one day

30
Q

What are external factors that can influence hazards?

A

Environmental conditions —> hot/cold
Control measures present —> being used in handle chemicals
How product is used
Other hazards present

31
Q

What are synergistic effects?

A

Two chemicals synergies to make the chemical more potent, heightened impact of affecting

32
Q

What are additive effect?

A

2 chemicals, the sum of two chemicals

33
Q

What are the three most common routes of exposure?

A

Inhalation
Absorption
Ingestion

34
Q

What is inhalation?

A

Breathing of contaminated air is common way that workplace chemicals enter the body

35
Q

What is absorption?

A

Skin contact, chemicals, when contaminated can pass through the skin into the blood stream

36
Q

What is ingestion?

A

Workplace chemicals may be swallowed accidentally if food or cigarettes are contaminated

37
Q

What are the other less common routes for exposure?

A

Injection and eye contact

38
Q

What is the hazard pathway?

A

The pathway that we can get expose to hazards, allows us to implement where and what type of control measures we can implement

39
Q

What are the effects of exposure?

A

Acute effects and chronic effects

40
Q

What are acute effects?

A

Sudden, severe, typically involves one incident, causes immediate problems
Not due to accumulation over time
Often associated with safety hazards

41
Q

What are chronic effects?

A

Continual exposure over time, limited concentrations of toxic substances, progressive accumulation of toxic substances in the body, little or no awareness of affected workers
Due to limited continual exposure over time
Often associated with occupational hygiene

42
Q

What are control measures?

A

Implementation of control measures to minimize risk of hazards

43
Q

What are the hierarchy of controls from most effective to least effective?

A
  1. Remove/eliminate the hazard
  2. substitute/ replace the hazard
  3. Engineering controls/ isolate people from the hazard
  4. Administrative controls, change the way people work
  5. PPE/ protect worker with personal protective equipment
44
Q

Which hierarchy of controls should you start with?

A

Engineering controls/ isolate people from hazard
