The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC andthe standard EN 374 derived from it.

Body ProtectionComplete suit protecting against chemicals, Flame retardant antistatic protective clothing, The typeof protective equipment must be selected according to the concentration and amount of thedangerous substance at the specific workplace.

Respiratory protectionWhere risk assessment shows air-purifying respirators are appropriate use a full-face respirator

with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backupto engineering controls. If the respirator is the sole means of protection, use a full-face supplied airrespirator. Use respirators and components tested and approved under appropriate governmentstandards such as NIOSH (US) or CEN (EU).
