Safety for working with compressed Nitrogen

Applicable for Lorrca instruments with Oxygenscan

Please be aware of the danger in terms of changing atmospheric levels of nitrogen or oxygen.

The biggest danger to lab personnel is a rapid depletion of oxygen levels in the lab.

O₂(Volume %)	Effects and symptoms on exposed
18-21	No noticable effect detected by the individual. Any source of gas contributing to change in atmosphere should be investigated and assessment carried out to determine whether environment is safe for continuation of work
11-18	Reduced physical and cognitive function without the individual realising
8-11	Possibility of sudden loss of consciousness. Risk of death below 11%
6-8	Loss of consciousness after a short time period, resuscitation possible if carried out immediately
0-6	Almost immediate loss of consciousness and brain damage highly likely

An oxygen meter can be used to detect rapid increasing gas levels in the working space.
