For example, when choosing safety helmet in low temperature working environment, plastic safety helmet with low temperature resistance should be selected (after low temperature - 20 ℃) ± 1n the environmental test at 2 ℃, the impact absorption performance and puncture resistance still meet the requirements of the standard) and the cold proof helmet; 1n high temperature working environment, high temperature resistant plastic safety helmet or glass fiber reinforced plastic safety helmet (after high temperature 50 ℃) should be selected ± The impact absorption and puncture resistance still meet the requirements of the standard when treated at 2 ℃); 1n electric power industry, safety helmet with electrical insulation should be selected when contacting power grid and electrical equipment; When working in inflammable and explosive environment, antistatic performance (resistance no more than 1 × one hundred and nine Ω) 1'm wearing a helmet (2) select according to the specification and size (3) the choice of style, big brim hat and big tongue hat are suitable for outdoor operation, this kind of safety helmet has the function of preventing sunlight and rain.
