WHAT IS A CONFINED SPACE?

A space that:

• Is large enough and so configured that an employee can enter bodily and perform work;

• Has limited or restricted means of entry or exit;

• Is not designed for continuous human occupancy.

Examples at Rig site…

• CELLAR AREA

• Tanks

• Pits

TANK

PIT

Main Hazards:

Toxic Atmosphere

Flammable substances

Oxygen enrichment / deficiency

Flowing Liquid or free flowing solids

Excessive heat

Hazards effects:

Fatality

Serious injury from fire or explosion

Loss of consciousness or asphyxiation from dangerous fumes etc.

Hazards

A safe system of work must be in place.

As per Saxon procedure for confined space (CAN-OFS-5.2-PRO-005:

Rev 02),

A competent person MUST have atmosphere tested the area. The test

must include the amount of oxygen, LEL % & H2S etc.

Oxygen must be between 19.5% and 21% for entry without a or SABA.

If the oxygen level is less than 19.5%, you must wear a SCBA or SABA.

If the oxygen level is more than 21%, the area must be evacuated

immediately and entry is not permitted.

Read and understand the Job Safety Analysis.

Obtain and use the correct PPE.

Inform your supervisor.

Each person must wear a Portable Air Monitor (PAM).

Do not enter alone ! FOR ANY REASON.

Watchman is mandatory.

What to do before entering a confined space ?

PAM

Precautions may be needed

• Tripod and fall arrestor

• Forced Air Ventilation

• Body harnesses

• Explosion proof lights

• Respiratory protection (SCBA or SABA)

Gas Test Results

Gas Test Results

Gas Test Results

Atmospheric air testing not carried out before entering confined space

Watch Man not available

Blower or equipment not available for proper air ventilation

Sometimes oxygen level is within limits but it is required to avoid

suffocation

Rotation of employee not carried out as per defined time period

Persons working inside confined space must switch their location

with watchman

Area not barricaded by caution tape or by hard barricading

Confined space entry checklist not used just Oxygen level written on

PTW

Permit end time not written on PTW form

Old permits not removed from PTW Board causing confusion

Previous Deficiencies related to Confined Space Entry

Evacuate the confined space

Don’t attempt the rescue yourself

Get help immediately!

Use emergency contact procedure

Give details of confined space location

Lead the professionals to the incident

Stay outside the confined space

What to do in case of any emergency?

Painting in Confined Space causes fire – 2 Fatalities

Employees in day shift painting in confined space continuously for

10 hours.

Lets watch a small video.

What went wrong?

Paint mixture was flammable.

Lighting equipment was not explosion proof

No ventilation and only one excess hole

Painters and labours enter confined space without any air space

monitoring.

No electrical connections within 50ft of hazardous atmospheres or

painting operations.

Employees not trained to identify confined space hazards.
