No protector can guarantee total protection!
Before you put it on, make sure the protector is complete and that no component is missing or damaged. Be aware that this individual protection equipment may not fulfil the purpose it is built for, if subjected to undue stress or if it suffers considerable damage.
Do not use at a temperature lower than 5?C, or higher than 35?C. Changes in environmental conditions such as temperature and humidity will significantly reduce the performance of the protection.
