Compliances for working at heights and in confined spaces


Compliance requirements when working at heights:

• ensuring safe access and egress

• installing guardrails around perimeters and penetrations

• setting up fall protection barriers (such as safety mesh or edge
protection)

• considering the risks involved from overhead services such as power
lines

• considering the risks involved from objects falling from height

• implementing a suitable means to prevent a fall.

n made sure any walking or working surfaces are strong enough to support workers safely and that any unprotected edges have fall protection in
place?

n made sure emergency procedures are in place should an accident occure or anything go wrong on site?

n made sure any necessary isolation procedures are in place (such as barricading and signage below the area of work to prevent workers or
passers by from being harmed from tools or material which may be dislodged from above)?

n provided anchorage points compatible with any fall arrest system (such as a
safety harness) being used?



Compliance requirements needed to work in confined spaces:


SECURING A SAFE ATMOSPHERE:

Employers should ensure that a competent person assesses the atmospheric contaminants before entry.


RISK ASSESSMENT:

The Standard emphasises that the employer must ensure that a risk assessment is under taken by a competent person before work begin.


RESPIRATOR CHOICE:

The responsible person controlling the operation should aim to achieve a safe atmosphere where respirators are not necessary.  If this is not practicable, an appropriate respirator should be considered.


ATMOSPHERIC TESTING:

The standard emphasises that before a person enters a confined space, testing is carried out to ensure that:

(a) the confined space contains a safe level of oxygen;

(b) atmospheric contaminants in the confined space are reduced to a safe level;

(c) the confined space is free from extremes of temperature;

(d) the concentration of flammable contaminant in the atmosphere is 0% of the Lower Explosive Limit (LEL) if hot work is to be carried out, or 10% if cold work is to be carried out.
