Hazards

Question 1

what is the hazard control programme made up of

Answer 1

• all the steps requirede to protect the workers from exposure to substances or systems
• conducting a RA to evaluate and prioiritize the risks and hazards
• the procedures required to moniter the workers
  hazard control methods: permanent and temporary

Question 2

reasonably practicable

Answer 2

it is a cost benefit analysis used to determine the actions to be taken in response to an identified risk. the ‘cost’ can be time, effort, money;; the sacrifice involved

Question 3

what is as low as reasonably practicable ALARP

Answer 3

where level of risk meets effort. the point at which the level of risk will not decrease no matter how much more effort (cost, time money) you put in. it includes the region of acceptable and tolerable risk (region between low and high risk) where
acceptable risk: the controls put in place are adequate enough to achieve a level of risk that does not significantly affect human heatlh and
tolerable risk: the benefit of the activity outweighs the human cost of the risk

Question 4

what does being resonably practicable depend on

Answer 4

• the likelihood of the hazard or risk occuring
• the degree of harm that would result if the hazard or risk took place
• the avaliability of suitable ways to eliminate or minimize the risk
• the cost of minimizing or eliminating the risk
• what the person knows about the risk and ways of eliminating or minimizging it

Question 5

best practice vs standard practice

Answer 5

both effective and safe but the best practice is more effective than the satndard one

Question 6

list the hierarchy of controls from most to least effective

Answer 6

1) elimination of the source of hazard
2) substitute the hazard with something safer
3) engineering controls- (methods built into the design of the plant, equipment or process to minize hazard- isolate people from hazard)
4) administrative controls- change the way poeple word eg more breaks to avoid burnout etc
5) PPE

Question 7

3 basic types of engineering controls

Answer 7

Process control- adjusting and changing the way a job/activity/process is done to minimize the risks
Enclosure/isolation- keeping the selected hazard physically away from the worker
Ventilation- an effective means of controlling workplace exposure

Question 8

administrative controls

Answer 8

when used they should limit the worker’s exposure to the hazard by sceduling shorter work times, job ritation schedules and work-rest schedules and schedule maintenance or other high exposure activities when few workers are present.
it also includes work practices such as developing and inplemienting standard operating procedurs SOP, maintenance of equipment and training in the case of an emergy response.
also includes good housekeeping to avoid accumulation of hazardous materials. (day t day cleanup, waste disposal and removal of unused material)
