Confined Space Entry

3

A confined space is defined as a place which is substantially (though not always

entirely) enclosed and where serious injury can occur from hazardous substances or

processes within the space or nearby. (HSE: Safe Work in Confined Space L101 2014).

Is there a risk of one or more of the following?

1. Serious injury due to fire or explosion.

2. Loss of consciousness arising from increased body temp.

3. Loss of consciousness or asphyxiation arising from gas,

fumes, vapour or lack of oxygen.

4. Drowning from an increase in the level of liquid.

5. Asphyxiation arising from a free flowing solid or being

unable to reach a respirable environment due to being

trapped by such a free flowing solid.

or totally enclosed? This space is not a

Confined Space: Interpretation in a Shipyard

A confined space is often

confused in shipbuilding and

repair with a small, enclosed

space, or one with only one

entrance.

As the picture on the left

shows; confined spaces in

shipbuilding can be vast and

contain multiple access points.

If there is a specified risk

present (as discussed on the

flow chart) it is a confined

space under the regulations

and the risks must be

assessed with appropriate and

proportionate controls put in

place.

Version 1.0


There are a multitude of differing spaces within a shipyard that can be classified as a

confined space under the regulations; they can be on vessels, within caissons, within

dock control rooms, pump rooms and electrical service areas.

Confined Space: Interpretation in a Shipyard

Version 1.0


• The unit is now

substantially enclosed.

There is more than one

access point and

mechanical ventilation is in

place, however the hot

work tasks taking place

within this space will now

introduce a reasonably

foreseeable specified risk

thereby making this space

now a “confined Space”.

• The unit is in construction,

walls are now in place

dividing and partially

enclosing spaces, but not

substantially. Natural and

mechanical ventilation

ensures that the air flow is

sufficient despite the

welding fumes and the unit

is not at this point a

confined space.

New Build – Creating Confined Spaces

• The jig to build the unit on

is constructed within the

Construction Hall. The work

is in an enclosed Hall but

adequate ventilation via

open doorways and

extraction systems deem

the hall not to be a

“Confined Space”.

Cammell Laird

Confined Space

Procedure

Version 1.0


All Confined Space Assessments need to identify all hazards and risks associated with the task to be carried out within the space.

All controls must be listed to either minimise or eliminate the risks. Additional task based risk assessments can be produced from this.

All tools, materials and equipment to be used are listed in the Confined Space Assessment.

When conducting a Confined Space Assessment the emergency rescue arrangements / plan must be identified.

Confined Space Assessment

8

Version 1.0


Example Space Assessment

9

Version 1.0


Assessments Must Include:

All confined spaces require a Competent Person to carry out an atmospheric test of the space before anyone enters, they will test for oxygen levels, flammable and explosive gases / vapors. Depending on the space it may be tested daily or weekly. The frequency of testing will be determined by a prior risk assessment of the space.

Pre-entry testing and monitoring of/for:

Atmospheric conditions

Potential hazards in and around

the area

Atmospheric Testing

Version 1.0


Certificate of Entry

This is the gas free certificate

for entry and cold work that is

issued once the Competent

Analyst has passed the

confined space, the HSE

Advisor will only issue a PTW

if this certificate is valid.

Hot work is not permitted

under this certificate as the

Competent Analyst has only

gas tested for oxygen levels.

Version 1.0


Certificate for Hot Work

This is the gas free

certificate for hot work that

is issued once the

Competent Analyst has

passed the confined space

free of all flammable and

explosive gases and or

vapours, the HSE Advisor

will then confirm this prior to

any permit being issued for

hot work.

Version 1.0


For all confined space work the person in

charge of the job must raise a PTW at the

relevant Permit Control Centre.

A task based risk assessment is required

that will determine the type of permit

required: hot, cold, electrical or painting.

The Safety Advisor will ensure a space

assessment is carried out by both the

Supervisor (and his tradesmen) for the

physical hazards, and a Competent Person

for atmospheric hazards and that these are

annotated to the permit.

Supervisor will agree upon all safety

controls listed on the permit, communicate

these and the findings of the space

assessment to all entrants and ensure that

all controls are in place before anyone

enters the confined space.

The name(s) of all persons involved in the

task will go onto the permit.

CL Confined Space Procedure

Version 1.0


CL Confined Space Procedure on Vessels

14

• All Confined Space work is

located by a numbered pin

on the displayed general

arrangement drawing of the

vessel. The pins

correspond to the work

listed on the Confined

Space Log which identifies

the trade, location and the

name of the top man.

• The Standby Man takes a two way radio to remain in

contact with the Health & Safety and Security Departments

and also a tank entry register (right) that is completed at the

space and kept updated throughout the task. A designated

channel is kept for these communications, with the option

to utilise another channel for 2way communications

between entrants and Standby Man where required.

Version 1.0


Confined Space Entry Tags

15

An entry tag that is displaying the

green tag shows that the confined

space has been tested and passed, it

displays what type of work can be

carried out within the confined space

i.e. entry, hot or cold work. If the tag is

removed from the holder, on the back,

it will show who gas tested the space

and on what date.

An entry tag that is displaying

the words “DO NOT ENTER”

dictates the space has not yet

been gas tested therefore

cannot be entered.

Version 1.0


Gas Monitors

Four way monitors

Carried on the person of

entrants

Personal Monitors Used at CL Safe Air Monitors Used at CL

Four way monitors

Remain in situ within the

confined space

• Where required, Cammell Laird uses both Personal Air Monitors (PAMS) and Safe

Air Monitors (SAMS) to monitor the atmosphere during entry into confined spaces.

The PAMS remain on the person of the entrants, whilst the SAMS are fixed into the

space and continuously monitor the atmosphere.

The Standby / Sentry MUST be trained and understand the roles and responsibilities of his/her job and should carry a 2 way radio at all times.

The Standby / Sentry is responsible for checking all PPE, safety equipment and rescue equipment is worn / in place before allowing anyone to enter the confined space.

The Standby remains outside the confined space and monitors the personnel working in the space. Regular communication.

The Standby monitors the surrounding area for hazards that may become present during the task.

The Standby should have a record of all personnel inside the space. He should have a completed Tank Entry Card on his person.

Version 1.0


Confined Space Rescue

If a personal gas monitor (or safe air monitor) alarms whilst in the

confined space then ALL personnel are to exit the space immediately,

the top man raises the alarm via radio. If emergency escape sets have

been deemed necessary by the risk assessment then they are worn

whilst exiting the confined space. If all entrants cannot exit the space

the Emergency Response Team will be called via radio to instigate first

response whilst the emergency services are on route. The ERT have

advanced first aid and will attempt to stabilise any casualty and provide

a supply of air until a rescue can be performed.
