The (type of laboratory—clinical or research) operates at biosafety level ________ as determined by (name of labora-tory director) for (organization’s name). This is in accordance with CDC/NIOSH Biosafety in Microbiological and Bio-medical Laboratories.
The following controls are in operation in the laboratory at this facility ________ (list controlled access, anterooms, sealed windows and other controls required in the standard and determined necessary by the laboratory director):

The procedures in this exposure control plan minimize the occupational exposure to TB. The procedures for isolating and managing care are used until the individual with suspected or confirmed infectious TB is determined to be nonin-fectious or until the diagnosis for TB is ruled out.
Recordkeeping
Any employee who has been occupationally exposed to anyone with a known case of active tuberculosis, and subse-quently develops a tuberculosis infection, the case must be recorded on the 300 log.
(Note: The following program is an example of a written program and based on the referenced standard. The standard does not require a written program, but as a best practice, it has been put into writing in this manual. Please modify or delete content to these policies as deemed necessary. Please reference the standard for all requirements that may be ap-plicable to your company.)
Walking and Working Surfaces Program (Ref. 29 CFR 1910.21–30)
There are many situations that may cause slips, trips, and falls, such as ice, wet spots, grease, polished floors, loose flooring or carpeting, uneven walking surfaces, clutter, electrical cords, open desk drawers and filing cabinets, and damaged ladder steps. The controls needed to prevent these hazards are usually obvious, but too often ignored, such as keeping walkways and stairs clear of scrap and debris; coiling up extension cords, lines, and hoses when not in use;
keeping electrical and other wires out of the way; wearing lug soles in icy weather; clearing parking lots, stairs, and walkways in snowy weather; and using salt/sand as needed.
Aisles and Passageways
l Aisles and passageways will be kept clear and in good repair with no obstruction across or in aisles that could create a hazard.
l Permanent aisles and passageways will be appropriately marked.
l Where mechanical handling equipment is used, aisles will be sufficiently wide. Improper aisle widths coupled with poor housekeeping and vehicle traffic can cause injury to employees, damage the equipment and material, and can limit egress in emergencies.
Floor Loading Protection
Load rating limits will be marked on plates and conspicuously posted. It will be prohibited to place, or cause or per-mit to be placed, a load greater than that for which such floor or roof is approved on any floor or roof of a building or other structure.
Guarding Floor and Wall Openings
Floor openings and holes, wall openings and holes, and the open sides of platforms may create hazards. People may fall through the openings or over the sides to the level below. Objects such as tools or parts may fall through the holes and strike people or damage machinery on lower levels.
Protection for Floor Openings
Standard railings will be provided on all exposed sides of a stairway opening, except at the stairway entrance. For in-frequently used stairways, where traffic across the opening prevents the use of a fixed standard railing, the guard will consist of a hinged floor opening cover of standard strength and construction along with removable standard railings on all exposed sides, except at the stairway entrance.
A “standard railing” consists of toprail, midrail and posts, and will have a vertical height of 42 inches nominal from the upper surface of toprail to floor, platform, runway, or ramp level. Nominal height of midrail is 21 inches. A “stan-dard toeboard” is 4 inches nominal in vertical height, with not more than 1⁄4-inch clearance above floor level.
Floor openings may be covered rather than guarded with rails. When the floor opening cover is removed, a tempo-rary guardrail will be in place or an attendant will be stationed at the opening to warn personnel.
Every floor hole into which people can accidentally walk will be guarded by either:
l A standard railing with toeboard, or
l A floor hole cover of standard strength and construction. While the cover is not in place, the floor hole will be constantly attended by someone or will be protected by a removable standard railing.
Stairway Railings and Guards
Every flight of stairs with four or more risers will have standard stair railings or standard handrails as specified below. Stair width is measured clear of all obstructions except handrails.
l On stairways less than 44 inches wide having both sides enclosed, at least one handrail will be affixed, preferably on the right side descending.
l On stairways less than 44 inches wide with one open side, at least one stair rail will be affixed on the open side.
l On stairways less than 44 inches wide having both sides open, two stair rails will be provided, one for each side.
l On stairways more than 44 inches wide, but less than 88 inches, one handrail will be provided on each enclosed side and one stair rail on each open side.
l On stairways 88 inches or more in width, one handrail will be provided on each enclosed side, one stair rail on each open side, and one intermediate stair rail placed approximately in the middle of the stairs.
A “standard stair railing” (stair rail) will be of construction similar to a standard railing, but the vertical height will be not more than 34 inches nor less than 30 inches from the upper surface of the toprail to the surface of the tread in line with the face of the riser at the forward edge of the tread.
