Q

What are Workplace Exposure Limits (WEL)?

A

Workplace exposure limits typically include two types of exposure levels: Short-Term Exposure Limits (STEL) and Long-Term Exposure Limits (TWA).

16
Q

What is Short-Term Exposure Limit (STEL)?

A

STEL refers to the maximum concentration of a substance that a worker can be exposed to for a short duration, usually averaged over a 15-minute period.

17
Q

What is the purpose of Short-Term Exposure Limits (STEL)?

A

protect workers from acute effects that might occur from brief, extreme exposures.

18
Q

Give an example of Short-Term Exposure Limit (STEL).

A

If a hazardous gas has a STEL of 300 ppm, it means that workers can be exposed to this concentration for up to 15 minutes without adverse health effects. However, exposure should not exceed this level at any time.

Example of STEL usage.

19
Q

What is Long-Term Exposure Limit (TWA)?

A

The Time-Weighted Average (TWA) represents the average exposure over a typical 8-hour workday or a 40-hour work week.

20
Q

What is the purpose of Long-Term Exposure Limits (TWA)?

A

prevent long term health risk from law exposure to hazardous substenses

21
Q

Give an example of Long-Term Exposure Limit (TWA).

A

If a chemical has a TWA of 100 ppm, workers can be exposed to this level throughout their work shift without health effect.

Example of TWA usage.

22
Q

what are the human factor in work place?

A
  • misstaken action
    -misstaken priorities
    -mispreception
    -wilfulness
23
Q

what are the personal factor in work place?

A

-physical &cognitive (health and fitness , information , training )
-phsycological

24
Q

Examine the psychological factors influencing workplace safety.

A

Management Commitment:
* When management demonstrates a commitment to safety (e.g., allocating resources for safety
training and equipment), it bring up a culture of safety within the organization. Employees are more
likely to prioritize safety when they see their leaders valuing it.
* Individual Experience:
* Workers with previous experience in safety protocols are more likely to follow safety guidelines and
report hazards. Conversely, those with negative experiences may either become overly cautious or
dismissive of safety measures.
* Peer Influence:
* Peer behaviors can significantly affect individual safety practices. If employees observe their
colleagues neglecting safety protocols, they may feel pressured to do the same. Conversely, a
positive peer culture can reinforce safe practices

25
Q

short-term controling methods

A

Engineering Controls: Use of local exhaust ventilation to quickly remove contaminants from the air.

  • Administrative Controls: Scheduling tasks to limit the number of employees exposed during peak times
26
Q

long term controling methods

A
  • Personal Protective Equipment (PPE): Providing respirators or protective clothing to reduce inhalation or skin
    contact.
  • Monitoring: Regularly measuring air quality to ensure levels remain within safe limits.
27
Q

List the controls that can be implemented to manage release hazards in the workplace

A

Simple Safety Measures:

Engineering Controls:
- Gas Detectors: Alarms that go off and shut off valves if there’s a gas leak (like methane detectors).

Administrative Controls:
- SOPs: Clear rules for safely handling and storing dangerous gases.
- Training: Regular sessions to teach workers how to spot and deal with gas leaks.

Personal Protective Equipment (PPE):
- Respirators: Masks for workers in areas with gas exposure.
- Gloves and Clothing: Protective gear for handling toxic gas containers.

Safe Storage Practices:
- Ventilation: Keep gas cylinders in places with good airflow to prevent gas buildup.
- Inspections: Regular checks of cylinders and equipment to find and fix problems early.
