6.3 toxicology test methods
Press the "disinfection technical specifications" of the relevant methods.
7 Use
Use Appendix A.
8 Precautions
8.1 Notice shall comply with relevant national standards set forth in the disinfectant, disinfectant not oral.
8.2 pairs of known infectious diseases excreta, secretions and body patient died of infectious diseases disinfection, there should be an appropriate level of personal protective
Measures. Unexplained infectious disease should be taken at the highest level of protective measures.
Disinfectant 8.3 users should do the appropriate protection, once the user has to happen disinfectants injury, should take timely response measures, and or
When medical treatment.
8.4 Some disinfectants to disinfect the object damage, should be based on the degree of valuable items, rational use of disinfection factor, it is necessary to ensure disinfection,
But also to minimize the extent of damage.
8.5 unmanned air disinfection should be, confined circumstances, after disinfection ventilation window.
8.6 less stable disinfectant now with the existing requirements, such as peracetic acid, chlorine disinfectant, bromine-containing disinfectants.
8.7 quaternary ammonium disinfectant, disinfectant can not be combined with guanidine soap anions.
8.8 pairs of flammable, explosive, volatile, corrosive disinfectants should be taken to prevent fire and explosion-proof, anti-corrosion measures and volatile.
Disinfectant dose 8.9 proposed standard does not apply to preventive disinfection.
