The document outlines a hazard checklist designed for identifying and analyzing safety, health, and environmental hazards in laboratory settings. It describes various hazard identification techniques such as HAZID, HAZOP, and FMEA, along with their advantages and disadvantages. Additionally, it emphasizes the importance of a structured approach to hazard analysis and provides examples of audit questions to ensure compliance and safety within laboratories.

A Hazard Checklist Contains Questions Or Topics Intended To Prompt
Consideration Of A Range Of Safety Issues. It Can Also Be Used In
Combination With Structured Hazard Identification (HAZID) Techniques
Such As SWIFT And HAZOP
Checklists Can Be Created From Previous Risk Assessments,And Provide
An Efficient Means Of Generating A List Of Standard Hazards Suitable For
HAZID Of Systems At All Phases Of Development.

5. INTRODUTION CONT’D
• The Checklist Should Be Constructed To Address A Range Of Safety
Issues Including Presence Of Hazardous Materials Or Functions,
Functional Performance, InteractionWith Other Systems,And Personnel
Safety. If Hazard Analysis Or Safety Assessment Has Already Been Carried
Out On A Similar System,Any Available And Relevant Information Should
Be Incorporated Into The Checklist.

11. HAZARD CHECKLIST QUESTIONS INCLUDE
Signage: Ensure that the laboratory has appropriate signage for the hazards present, such as
biohazard level, radiation, or laser
Access: Restrict access to the lab to authorized personnel
Personal protective equipment: Ensure that personnel wear the appropriate personal
protective equipment, such as closed-toe shoes, long pants, and a lab coat
Chemical storage: Ensure that chemicals are stored properly, including separating
incompatible chemicals, storing flammable liquids away from heat, and storing highly toxic
chemicals in locked cabinets

12. HAZARD CHECKLIST QUESTIONS INCLUDE
Safety equipment: Ensure that safety equipment, such as safety showers and eye wash stations, are
available and in good working order
Electrical safety: Ensure that electrical cords are not a tripping hazard, and that damaged cords,
outlets, or plugs are repaired
Housekeeping: Ensure that the lab is clean, orderly, and uncluttered
Emergency procedures: Ensure that emergency notification procedures, contacts, and phone
numbers are posted
First aid: Ensure that a first aid kit is readily accessible and adequately stocked

14. HAZARD CHECKLISTS CONSIDERATION
When setting up and using a Hazard Checklist, the following points should be considered:
A Hazard checklist is useful for most risk assessments, but should not be the only HAZID
method, except for standard installations whose hazards have been studied in more detail
elsewhere.
The topics presented in any Hazard Checklist should not be considered to be
comprehensive; they are for guidance, and are the minimum that should be considered.
For greatest benefit, Hazard checklists should be applied in an imaginative way by those with
a good understanding of the system design, operation, location, upkeep and interactions.

15. HAZID
HAZID is a risk identification technique that aims to identify
potential hazards associated with a process, system, or
operation. It involves systematic brainstorming sessions
involving subject matter experts to list and analyze potential
hazards

16. HAZOP
Hazard and Operability (HAZOP)
study is a structured and systematic
examination of a planned or existing
process or operation in order to
identify and evaluate problems that
may represent risks to personnel or
equipment, or prevent efficient
operation

17. FAILURE MODES AND EFFECTS ANALYSIS (FMEA)
It was one of the first systematic techniques for failure analysis. It was developed in the United
States military (Military Procedure MIL-P-1629, titled ‘Procedures for Performing a Failure
Modes, Effects and Criticality Analysis’, November 9, 1949) as a reliability evaluation technique to
determine the effect of system and equipment failures.
Failures were classified according to their impact on mission success and personnel, equipment
and safety. In the 1960’s it was used by the aerospace industry and NASA during the Apollo
program. More and more industries - notably the automotive industry - have seen the benefits
to be gained by using FMEAs to complement their design processes.

18. FMEA
This qualitative technique helps identify failure
potential in a design or process i.e. to foresee
failure before it actually happens.This is done
defining the system which is under
consideration to ensure system boundaries are
established and then by following a procedure
which helps to identify design features or
process operations that could fail.The
procedure requires the following essential
questions to be asked:
• How can each component fail?
• What might cause these modes of failure?
• What could the effects be if these failures did occur?
• How serious are these failure modes?
• How is each failure mode detected?
• What are the safeguards in place to protect against
accidents resulting from the failure mode?

19. SWIFT
The Structured What-If Checklist Technique (SWIFT) combines the use of
checklists with a brainstorming ‘What if?’ approach. It was initially developed
for hazard identification in the chemical process industry.The technique was
developed as an efficient alternative to HAZOP for providing highly effective
hazard identification in situations and systems where HAZOP is not
appropriate. SWIFT can also be used in conjunction with or complementary
to a HAZOP.

20. SWIFT
Its effectiveness in identifying hazards comes from asking questions in
a variety of important areas, according to a structured plan.The aim is
to ensure complete coverage of all the various types of failures or
errors which are likely to result in a hazard within the system being
examined.

21. SWIFT
The “What-if?” questions, which can be posed by any team member (including
the SWIFT leader and Recorder) are structured according to various question
categories.The SWIFT analysis is further strengthened through the use of
category specific checklists at the conclusion of each question category
resulting in an additional level of thoroughness. Information resulting from the
SWIFT meeting is recorded on logsheets in columns as “What If”,
“Consequences”,“Existing Safeguards” and “Recommendations”.

22. ADVANTAGES OF HAZARD CHECKLIST
• Makes use of experience from previous risk assessments.
• Supports rapid and full Hazard Identification of common systems and technologies.
• Helps to prevent past accidents from recurring.
• Promotes standard hazard categories, and facilitates comparison between HAZIDs.
• Can be prepared and applied by a single analyst at low cost.
• Requires minimal information about the installation, and so is suitable for concept design

23. DISADVANTAGES OF HAZARD CHECKLIST
• Limited to previous experience, and thus may not anticipate hazards in
novel designs or novel accident scenarios from existing designs.
• Bounded in nature and thus does not encourage imaginative thinking.The
technique is therefore often used only as a prompt if ideas are dwindling
or as a final review/check at the end of the Hazard identification exercise.
