Regulation X Other Reasons
Employee Health/Exposure Control Plan
The Northfield School District is committed to providing a safe and healthful work environment for our entire staff. In pursuit of this goal, the following exposure control plan (ECP) is provided to eliminate or minimize occupational exposure to blood borne pathogens in accordance with OSHA standard 29 CFR 19 10.1030, “Occupational Exposure to Blood borne Pathogens.”
The ECP is a key document to assist the district in implementing and ensuring compliance with the standard, thereby protecting our employees. This ECP includes:
- Determination of employee exposure;
- Implementation of various methods of exposure control, including:
- Universal/standard precautions;
- Engineering and work practice controls;
- Personal protective equipment;
- Hepatitis B vaccination;
- Post-exposure evaluation and follow-up;
- Communication of hazards to employees and training;
- Procedures for evaluating circumstances surrounding exposure incidents.
Implementation methods for these elements of the standard are discussed in the subsequent pages of this ECP.
The following chart lists the staff members responsible for the implementation of the regulation and summarizes their responsibilities:
|Position||Summary of Main Responsibilities|
|Board of Education||
Exposure Control Coordinator for the district
Exposure Control Officer in the School
|Teaching and support staff||
|Athletic Director and athletic staff (volunteers if applicable)||
“Standard” or “universal precautions” as defined by the Centers for Disease Control (CDC) are a set of precautions designed to prevent transmission of HIV, Hepatitis B virus (HBV), and other blood-borne pathogens when providing first aid or health care. Under standard precautions, blood and certain body fluids of all patients are considered potentially infectious for HIV, HBV and other blood-borne pathogens.
Standard precautions include:
- Every person should be treated as though they have an infectious disease;
- Protective barriers;
- Proper hand washing;
- Appropriate disposal of hazardous waste;
- Proper cleaning of contaminated areas.
“Blood-borne pathogens” means pathogenic microorganisms that are present in human blood and can cause disease in humans. These pathogens include, but are not limited to, hepatitis B virus (HBV) and human immunodeficiency virus (HIV).
- Body fluids that carry blood-borne pathogens:
- Semen and vaginal secretions
- Cerebrospinal fluid
- Pleural fluid
- Peritoneal fluid
- Pericardial fluid
- Amniotic fluid
- Body fluids that do not NORMALLY carry blood-borne pathogens (Note – blood may sporadically appear in such fluids, in which case precautions should be taken):
- Nasal secretions
“Exposure Incident” means a specific eye, mouth, other mucous membrane, non-intact skin, or parenteral contact with blood or other potentially infectious materials that results from the performance of an employee’s duties.
“Parenteral” means piercing mucous membranes or the skin barrier through such events as needle sticks, human bites, cuts, and abrasions.
