Minimum Ppe Requirements in the Lab
Nov 23 2022

Laboratory visitors: Safety glasses are the minimum PPE requirements for a non-contact visit to a laboratory or other areas where chemical, biological, radiological or mechanical hazards exist. For laboratories where chemical, biological or radiological hazards may pose a risk to the visitor, a laboratory gown must also be provided. Biosafety level requirements apply to a wide range of industries, including biomedical, pharmacological, environmental, environmental and biological research. Staff/Students/Volunteers Working in a Laboratory: A lab coat, goggles, long pants and closed shoes are the minimum PPE for working in a laboratory where chemical, biological, radiological or mechanical hazards are present. These garments shall, if necessary, be supplemented by gloves and other appropriate personal protective equipment (PPE) necessary for the tasks to be performed. It is important for anyone working in a biological laboratory to understand the four different biosafety level requirements as well as the specific requirements of their laboratory, based on the laboratory`s BSL assessment. Let`s take a closer look at specific security practices, typical activities or tasks, and staff access restrictions at each biosecurity level. (Personal protective equipment for biosafety laboratories is explained in the next section.) If your duties are not limited to standard laboratory work and related PPE requirements, please refer to the Occupational Health and Safety PPE page. Examples include steel shoes to protect against falling or rolling heavy objects, or cut-resistant gloves when working with sharp objects Personal protective equipment (PPE) adapted to working conditions should be worn when working with laboratory hazards. Personnel should be closely monitored for signs and symptoms of illness. Records must be kept of the date and time of all persons, equipment and supplies entering and leaving the entry and exclusion zones.

All materials leaving the laboratory room must be thoroughly decontaminated. Laboratories called LSA-2 involve working with agents or organisms associated with human diseases that pose moderate risks to humans and the environment. Finally, laboratory staff must change before entering the laboratory and take a shower before leaving the laboratory room. There are four BSL levels or grades ranging from BSL-1 to BSL-4. The BSL value of a laboratory is mainly based on the active substances or organisms found in that particular laboratory. Other factors to consider when determining laboratory concentrations include: Personal protective equipment for biosafety laboratories can be classified as follows: Research laboratories and biomedical laboratories often work with living and potentially hazardous microorganisms. For this reason, laboratory models, laboratory safety procedures and special personal protective equipment for biosafety laboratories must be in place to prevent contamination or accidental release of these contaminants. External personnel often have limited access to BSL-2 laboratories when the work is performed. An example of an organism that could be studied in a BSL-1 laboratory would be the non-lethal agent E. coli.

Laboratories labeled BSL-4 must comply with all considerations of BSL-3 and must also undergo daily inspections of facilities and equipment, as well as Class III biological safety cabinets for all work with organisms. Biosafety levels determine the type of work or research that can take place in a particular laboratory, as well as the type of organisms that can be used or studied there. The level of biosecurity even influences the overall design of the plant and the special safety equipment inside. In addition to standard microbial practices, BSL-2 laboratories will also have additional safety practices: BSL-3 laboratories will have restricted and controlled access at all times. The primary methods of protecting laboratory personnel and students from hazards such as chemical, biological, radiological, physical and mechanical hazards in the workplace are disposal, engineering and administrative controls. If these control methods are not appropriate or sufficient to control the hazard, personal protective equipment (PPE) is required. PPE is also required in conjunction with other controls to mitigate the effects in the event of an incident. For more information on general PPE guidelines, please visit the PPE for Personal Protective Equipment website. In addition to routine microbial practices, individuals working in BSL-3 laboratories are medically monitored and may need to be vaccinated against the organisms or pathogens they work with.

Any work with organisms must be carried out inside a BSC and autoclaves are generally used. There are a number of safety equipment suppliers that sell a variety of personal protective equipment.
