Confined Spaces - ProMinent DULCOMETER PH-501 Assembly And Operating Instructions Manual

When equipment is to be locked out, employers, supervisors and workers should follow
accepted lockout principles, including:
Pre-planning for the lockout by identifying all energy sources, switches, etc.
Where lockout is complex, a written sequence in checklist form should be prepared for
equipment access, lockout/tagout, clearance, release and start-up.
All workers affected by the lockout should be notified.
Equipment should be shut down by normal means by turning of switches and closing
valves etc.
Equipment should be isolated from energy sources by disconnecting or blocking the
sources of energy.
Lockout and tag the energy isolating devices by padlock or some other locking device that
the worker has control over as well as a tag indicating that the equipment has been shut
down.
Verify that all energy sources have been isolated by attempting to cycle the equipment
prior to working on it.
When work is completed, release equipment from lockout.

Confined Spaces

"confined space" means a fully or partially enclosed space:
that is not both designed and constructed for continuous human occupancy, and
in which atmospheric hazards may occur because of its construction, location or
contents or because of work that is done in it.
If you have a space that is fully or partially enclosed, the two conditions – (a) and (b) above –
must both apply before the space can be considered a "confined space".
"atmospheric hazards" means:
the accumulation of flammable, combustible or explosive agents,
an oxygen content in the atmosphere that is less than 19.5 per cent or more than 23 per
cent by volume, or
the accumulation of atmospheric contaminants, including gases, vapours, fumes, dusts or
mists, that could,
o result in acute health effects that pose an immediate threat to life, or
o interfere with a person's ability to escape unaided from a confined space.
Follow local laws and regulations with respect to entering a confined space.
