A separate

decontamination area

shall be established by

using (where

practicable) a second

sheet of plastic for

decontamination

activities. Where this is

not possible due to

wind or restricted

access then a larger

sheet of plastic may be

used, it shall we

Where pit was in close

proximity to a structure

such as a fence,

building or post box,

use a damp cloth to

wipe down the

structure. Dispose of

cloths in an asbestos

disposal bag.

Do not resoak rags in a

bucket of water as this

will contaminate the

water. Instead, fold the

rag so that a clean

surface is exposed or

use another rag. Place

contaminated rag in

Contamination of Tools 2 3 M5

All hand tools used

during the breaking up

decontaminated.

Workers involved in the

ACM removal work and

are wearing the

required PPE may

participate in

decontamination.

DO NOT BREAK UP

FURTHER, double wrap

them in 200 micron

the process above, c.

Use asbestos warning
