✓ Autoclavable bag
✓ Latex or Nitrile gloves
✓ Forceps for picking up broken glass
✓ Biohazard Bag(s)
It isolates people from the hazard by placing a barrier between the worker and the hazard. Favored over administrative and your PPE equipment for controlling existing worker exposure in the workplace because they are design to remove the hazard at the source before it comes in contact with the worker.
Engineering Controls
Limits the duration of working time of the workers at a hazardous place
Administrative Controls
Who performs the Administrative Control
Pathologist
Chief Medical Technologist
Used internationally to indicate the actual or potential presence of a biohazard and to identify equipment, containers, rooms, materials, experimental animals or combinations thereof that contain ,or are contaminated with, viable hazardous agents.
Biohazard Symbol
treat all human blood and certain human body fluids as if they were known to be infectious for HIV, HBV and other blood-borne pathogens.
Universal Precaution
minimum infection prevention practices that apply to all patient care, regardless of suspected or confirmed infection status of the patient
Standard Precaution
set of infection control practices used to prevent transmission of diseases that can be acquired by contact with blood, body fluids, non-intact skin (including rashes), and mucous membranes

PPE (Personal Protective Equipment)
The most effective control measure
Elimination
If a particular dangerous chemical or work process cannot be completely eliminated, then try to replace it with a safer
Substitution
By using a mechanical handling device or a closed glove system that can be operated from the outside
Enclosure
Can be effective method of control if a hazardous job can be moved to a part of the workplace where fewer people will be exposed, or if a job can be changed to a shift when fewer people are exposed (such as a weekend or midnight shift)
Isolation
To prevent the work environment from being too hot, cold, dry, or humid
To prevent contaminants in the air from getting into the area where workers breathe
Ventilation
removing air pollutants
Local exhaust ventilation
can be used for keeping the workplace comfortable
