Artifact Cleaning Procedures
Title: Biological Hazards Risk Control Procedure
Applies to: All Employees and Volunteers
Revision Date: June 1996
Operating Bird and animal droppings contain biological hazards which
can be
Principle: harmful to people. This procedure is intended to provide
assistance to employees and volunteers in reducing that risk.
Details: Mandatory Work Procedures
Where exposure to biological hazards is expected, workers and
volunteers are required to wear respiratory protective equipment
equipped with high efficiency particulate (HEPA) filters.
Disposable HEPA filter dust masks will be provided by Doon.
Training on maintenance and fit-testing of the masks will be part
of the program.
Workers and volunteers must also wear disposable latex or vinyl
gloves which will be provided by Doon.
If the level of contamination of the artifact is significant,
goggles are mandatory. In other situations goggles are a
recommended piece of personal protective equipment. Several
pairs of goggles will be provided for staff and volunteers to use
when needed. Proper cleaning of the equipment before and after
use is imperative and disinfectant wipes will be provided for
this purpose.
Proper personal hygiene is also very important, and workers and
volunteers should wash thoroughly after handling artifacts and
prior to eating or drinking.
Recommended Work Practices
During general handling and cleaning activities where heavy
accumulations of droppings are NOT present, goggles are a
recommended piece of personal protective equipment. Heavy
accumulations of droppings require goggles at all times.
It is recommended that you bring a set of work clothes with you

launder them right away.
