Be sure all flammables (e.g. fuels and gas cylinder) and obstacles (e.g. tools, vehicles, wastes and
other materials) are clear of work site to secure safe work site.
Check and record the conditions at site, such as geographical features and soil, for potential
hazards.
Take precautions to minimize hazards. For example, make trespassing-prohibited area for a
dangerous place. Put safety guards securely in place. Reinforce the ground.
