Risk Assessment & Chemical Risk

«Chimie verte» : Mythe ou réalité ? Chemical Safety Training

Lab Safety

“It is imperative to know and

understand the risks along with the

techniques and equipment to reduce

them to an acceptable level”

Implement security

measures

Assess the risks associated with

the protocol

Know emergency procedures

Identify hazards

3


WHAT LAB SAFETY MEANS TO YOU ?

4


4 Questions to answer

• What are the hazards?

• What are the worst things that could happen?

• How can I be prepared?

• What are the most prudent practices, protective

facilities/equipment, and personal protective equipment

for minimizing the risks?

Lab Safety 5


Legislation

• LAW C-21

Bill C-45 amends the Criminal Code regarding criminal liability of

organizations. This law facilitates the prosecution of organizations

and their leaders in case of negligence or fraud, such as accidents.

7 Due Diligence

Implement appropriate solutions, including clear

guidelines and procedures, and periodically

reassessing the situation;

Do not accept dangerous

behaviours in health and safety,

including inappropriate and

remedial measures

Identify risks

related to

work and

develop the

tools to

reduce and

control

them;

Make these procedures

known and establish an

information system;

Ensure individuals who

perform the tasks are

adequately trained;

Spill on yourself, other than HF

36


Seek fresh air, do not forget to warn

someone in the lab

Chemical inhalation



• Before leaving the lab

Check any overnight reactions

Turn off the lights and electrical equipment

Check water and gas cylinder gas

Clean your bench and your workspace
