Study Notes

Lab Coats

Typically button or snap up the front
Should cover the entire upper body and extend to the knees
Must fit comfortably without hanging loosely
Need fitted wristbands to prevent splashes up the arm
Should be made of fire-retardant material when working with fire hazards
- 35% polyester and 65% cotton blends are commonly used
- Cotton has semi-fire-retardant properties, while polyester resists chemicals
Should be laundered by an approved vendor based on lab policy

Gowns

Consist of a solid, impermeable front, tied at the back, neck, or sides
Offer broader protection than lab coats and are used in higher-risk settings
Can be worn over clothing or a lab coat
Can be made of disposable or reusable material, sometimes called "isolation gowns"

Aprons

Used for additional splash protection, especially when:
- Removing liquid nitrogen
- Handling large volumes of liquids or corrosive chemicals
- Performing autopsies or necropsies
- Manipulating chemicals that increase the likelihood of splashes
Commonly made of plastic, vinyl, PVC, neoprene, or rubber
Rubber is best for protection against corrosive or irritating liquids
Should fit comfortably and extend from below the neck to above the feet

Safety Glasses

Required when working with hazardous materials, especially when there is a splash hazard

Hierarchy of Safety Control (CDC and NIOSH)

The primary method is to eliminate the hazard(s), followed by substitution
Next, utilize engineering and administrative controls to reduce hazards
PPE is typically required when other controls are insufficient and can be used in combination with other methods

PPE Commonly Used in Clinical Labs

Body Protection:
- Lab coats, gowns, and aprons
Eye and Face Protection:
- Safety glasses, goggles, face shields
Hand Protection:
- Latex, nitrile, insulated, and chemically resistant gloves
Respiratory Protection:
- Face masks and respirators
Other Considerations:
- Foot protection
- Sleeve guards
- Personnel clothing and dress codes

Lab Glass Disposal

Lab glass (including plastic ware) must be placed in sturdy cardboard boxes for safety during transport
Boxes should not be used for:
- Sharps
- Biohazardous materials that have not been autoclaved
- Liquid wastes
- Chemically contaminated glassware / plastic ware
- Chemical containers that cannot be disposed of as regular solid waste

Chemical Exposure and Storage

Toxic chemicals can enter the body through:
- Inhalation (major route for solvents)
- Absorption through the skin (produces systemic poisoning; rate depends on skin condition)
- Ingestion (accidental, usually due to poor hygiene)
All chemicals, including solutions and transfers, should be labeled with:
- Common names
- Concentrations
- Hazards
- Date received
- Date opened
- Date of expiration
Store corrosive, toxic, and highly reactive chemicals in a well-ventilated area
Store chemicals that can ignite at room temperature in a flammables cabinet

Radiochemicals

Require special precautions and dedicated benches with specific bench covers
Specific storage areas for radioactive materials are needed and must provide:
- Appropriate protection (plexiglass, lead)
- Specific waste containers based on the chemical nature of the waste and radio elements

Laboratory Safety

A laboratory safety program is essential to protect employees, patients, laboratory equipment, and the environment.
Negligence in laboratory safety can result in:
- Loss of reputation
- Loss of customers/income
- Negative effects on staff retention
- Increased costs: litigation, insurance
Laboratory managers should:
- Participate in the design and planning of new laboratory facilities
- Conduct risk assessments and apply organizational concepts to create a safe environment for laboratory activities
- Consider laboratory organization when developing new activities or techniques

Laboratory Design

Patients and patient samples should not have common pathways.
Contaminated laboratory glass must be disposed of in sturdy cardboard boxes weighing no more than 40 pounds.
Do not use boxes for:
- Sharps
- Biohazardous materials that have not been autoclaved
- Liquid wastes
- Chemically contaminated laboratory glassware/plastic wares
- Chemical containers not suitable for regular solid waste disposal

Chemical Safety

Chemicals should be labeled with their common names, concentrations, and hazards.
Store corrosive, toxic, and reactive chemicals in a well-ventilated area.
Flammable chemicals should be stored in a flammables cabinet.
Radioactive materials require specialized storage areas with protective measures (plexiglass, lead) and dedicated waste containers.

Gloves

Disposable gloves should not be reused or disinfected.
Reusable gloves should be washed routinely and air-dried before reuse.
Gloves should not be worn outside of the laboratory.
Gloves should be resistant to the chemicals being handled while maintaining dexterity for the wearer.

Types of Gloves

Latex gloves offer protection against biological hazards but not chemical hazards.
Nitrile gloves are widely used in labs for their protection against infectious material and various hazardous chemicals.
Insulated gloves provide protection against extreme temperatures.
Chemical-resistant gloves provide protection against specific chemical hazards.

Personal Protective Equipment (PPE)

A PPE program should include:
- Hazard and risk identification and mitigation
- PPE selection, maintenance, and use
- PPE training for employees
- Monitoring the effectiveness of the PPE program
- Providing PPE for free to staff

PPE Selection

PPE should meet national and state safety requirements and recommendations.
PPE should be available in a range of sizes for staff.
PPE should protect personal clothing and skin from contamination.
PPE effectiveness should be assessed, ensuring it serves as a primary barrier against hazards or complements other controls.

PPE Training

Employers should provide training to each worker using PPE on:
- When PPE is necessary
- The type of PPE needed
- How to properly don, adjust, wear, and doff PPE
- The limitations of PPE
- Proper maintenance, use, and disposal of PPE
Laboratory management should ensure staff demonstrate competence in wearing and using PPE before performing work.
Retraining may be necessary if work conditions change or staff fail to demonstrate proper PPE use.

Employer Responsibilities for PPE

Employers are required to:
- Conduct hazard assessments to determine appropriate PPE.
- Provide PPE to employees at no cost.
- Train employees in the use and care of PPE.
- Establish a PPE maintenance program, including replacement of worn or damaged PPE.

Employee Responsibilities for PPE

Employees are responsible for:
- Properly wearing, using, and disposing of PPE.
- Attending PPE training sessions.
- Notifying the lab manager, supervisor, or safety officer about the need for new or additional PPE.

PPE in Laboratory Settings

Most clinical laboratories operate at BSL-2 level.
Typical PPE for BSL-2 settings includes:
- Lab coat or gown (at times)
- Gloves (nitrile)
- Safety glasses or face shields (at times)
- Respiratory protection (at times)
Additional PPE may be required based on risk assessment findings.
