Where temporary heating is used the employer ensures that liquid fuel or gas kept beyond what one day needs is stored safely and as Part 7 requires, that fuel-fired heating devices and temporary furnaces stand on the ground or a non-combustible floor (or on 76 mm of non-combustible material over wood) with the prescribed clearances and venting, that portable heaters are not used in confined spaces or placed in or next to a means of egress, that an approved extinguisher of adequate size is at hand at every temporary heating device, and that temporary steam piping is securely supported and insulated or guarded where workers could touch it.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
