Respiratory Protection, OSHA 1910.134
Respiratory protection training of employees is required before use and annually thereafter.  Only those employees who are medically approved may wear respiratory protection.  Within the funeral service industry, respirators are typically worn for protection against formaldehyde vapor, suspected active tuberculosis cases, and for general odor protection.  
Ecolomed updates its training material at least annually and/or when warranted by pertinent regulatory changes.
