First of all, you need to check whether the electrical equipment is appropriate for the job. Make sure that the construction of the equipment makes it safe enough. Define any safety hazards that there might be and decide which is the best solution for them.It is inappropriate to use electrical equipment in a damp environment. It is a better idea if you use air powered equipment instead, or any other equipment that runs on low voltage transformers or batteries. Precautions regarding safety should be taken in a more strict way if the workplace has an explosive atmosphere due to the presence of flammable gases and aerosols.
