Review the key hazards, consequences and control measures for Leak Testing in a structured professional HSE format.

01
Hazard

Pressurized fluid release

Potential Consequence

Impact or injection injury

Persons at Risk

Test team

Existing Controls

Controlled test pressure and exclusion zone

Additional Controls

Never use hands or body to locate a leak

02
Hazard

Hazardous test gas or fluid

Potential Consequence

Exposure or asphyxiation

Persons at Risk

Test personnel

Existing Controls

Suitable test medium and ventilation

Additional Controls

Assess atmospheric effects of test medium in enclosed areas

03
Hazard

Connection failure

Potential Consequence

Hose whip or projectile

Persons at Risk

Test team

Existing Controls

Connection inspection

Additional Controls

Use safety restraints where required

04
Hazard

Pressurized release during leak test

Potential Consequence

Impact or serious injury

Persons at Risk

Test personnel

Existing Controls

Controlled test procedure and exclusion zone

Additional Controls

Maintain test pressure within procedure limits and clear line-of-fire areas

05
Hazard

Exposure to leak-detection chemical

Potential Consequence

Skin or eye irritation

Persons at Risk

Test personnel

Existing Controls

SDS and suitable PPE

Additional Controls

Follow SDS requirements for the leak-detection product

06
Hazard

Residual pressure after leak testing

Potential Consequence

Sudden pressure release

Persons at Risk

Test and maintenance personnel

Existing Controls

Controlled depressurization

Additional Controls

Verify zero pressure before disconnecting equipment

07
Hazard

Personnel standing close to a connection during leak testing

Potential Consequence

Exposure to pressurized fluid following connection failure

Persons at Risk

Workers performing the activity and nearby personnel

Existing Controls

Authorized personnel, pre-work checks, suitable equipment and site procedures

Additional Controls

Maintain a safe distance around connections during testing

08
Hazard

Open flame used for leak detection

Potential Consequence

Fire, explosion or burn injury

Persons at Risk

Workers performing the activity and nearby personnel

Existing Controls

Authorized personnel, pre-work checks, suitable equipment and site procedures

Additional Controls

Use an approved leak-detection method and suitable detector

09
Hazard

Test pressure not released in a controlled manner

Potential Consequence

Sudden pressure release or hose movement

Persons at Risk

Workers performing the activity and nearby personnel

Existing Controls

Authorized personnel, pre-work checks, suitable equipment and site procedures

Additional Controls

Release test pressure in a controlled manner through the designated safe point
