Q

Why do we do a risk assessment?

A

· Obvious reasons: Reduction in injuries/illnesses, lost time, claims, insurance premiums
· Industry standards require risk assessments
· Customers are beginning to require risk assessment of sale
· Risk assessment works
· As a part of the code of ethics established by various professional organizations

Q

Explain Step 1: Set the limit of the assessment

A

These parameters can be the limits of the machine or design, limits on uses, limits on the scope of the analysis, or other limits

Q

How do you identify hazards (step 2)

A

· Physical inspection of the workplace
· Brainstorming
-Conducting group meetings with people who are familiar with the operation of the area under review
-Recording all ideas and thoughts relating to possible hazards -sorting the results into some type of priority order.

-Severity/impact

Q

What is risk ranking (step 3)

A

-Ranking Matrix combining risk elements of probability (frequency) and impact (severity).
-broken into map chat
-probability * impact = risk
-risk score is found

Q

Explain step 4 to reduce risks

A

-Remedy actions are taken to reduce risks following the hazard hierarchy control:
-Most to least effective (start from top first)
1. Eliminate through/by design
2. Protect (guarding)
3. Warn the User (awareness devices
4. Procedure/training
5. Personal Protective Equipment

Q

Explain step 5: Access Residual Risks

A

· Selected measures effectively reduced the risk
· Probability and severity are assessed to obtain residual risk level
· Aka does new safety implication still have risk(s) or new risks?

Q

Explain step 6: When to stop/Residual Acceptable

A

· This assessment verifies that the remedy actions have reduced the risks to an acceptable level.
· A decision shall be made to accept or further reduce the residual risk.

Q

What is an acceptable level of risk? (Step 6)

A
  • When it is insignificantly low
  • When we don’t know it’s there
  • When we are sure it is worth it

Q

Explain step 7: Results and Documentation

A

· The documentation can be added to a technical file for future use.

Document, Monitor, and Review
· Procedures that have been followed
· Identified hazards
· Risk reduction methods employed (eliminate or reduced to an acceptable level)
· Review what has been done to ensure that the controls put in place are effective.

Q

Other risk assessment steps

A
  1. Identify the hazards
  2. Decide who might be harmed and how
  3. Evaluate the risks and decide on precaution
  4. Record your findings and implement them
  5. Review your assessment and update if necessary

17
Q

What are the 2 barriers in risk assessment?

A

· Barrier 1
- Few design professionals possess sufficient expertise in safety

· Barrier 2
- Such processes (risk assessment to design in safety) will increase both direct and overhead costs for designers

18
Q

What is the solution to barrier 1 (Few design professionals possess sufficient expertise in safety)?

A
  • Add safety to design professional curriculum
  • Develop and promote 10 hour and 30 hour OSHA courses for design
    professionals
19
Q

What is the solution to barrier 2 (Such processes (risk assessment to design in safety) will increase both direct and overhead costs for designers)?

A

Educate owners that total project costs and total project life cycle costs will decrease

20
Q

What is the fail safe concept?

A

Things will fail so you should have a plan and document what you do

21
Q

What are the most to least influential steps in design that influence safety? (5)

A

Conceptual design, detailed engineering, procurement, construction, start-up
