Writing guidelines to require disinfection.
Disinfection, when performed correctly, is an important step in the control and elimination of specific disease agents. Typical disinfection instructions merely state that 'the premises or materials contaminated by or exposed to disease shall be disinfected'. Directions are rarely given on how to perform the job. The first stage in a complete and proper disinfection operation for materials and property involves a thorough assessment of the problem and the development of a step-by-step action plan. Detailed guidelines should address the relevant questions--who should do what? where, when and how?--in relation to each step of the job. It should be ensured that all work is correctly executed and reported, and a follow-up evaluation of the premises should be made to verify that the disease agent(s) have been destroyed. Persons using disinfectants should always follow safety precautions to avoid the risk of occupational injuries.
