Hazardous waste is a by-product of many industrial and manufacturing processes. The improper management and disposal of hazardous waste can have severe environmental and health consequences. It is crucial to handle hazardous waste safely, and one of the most important aspects of safe handling is choosing the appropriate personal protective equipment (PPE). In this article, we will discuss some practical tips for safely managing hazardous waste and the appropriate level of PPE for each situation.
Practical Tips for Safely Managing Hazardous Waste
Use Appropriate Level of PPE for Each Situation:
The appropriate levels of protective clothing when handling hazardous waste depend on the type and level of hazard involved. The Occupational Safety and Health Administration (OSHA) has established guidelines for the appropriate level of personal protective equipment (PPE) based on the nature and severity of the hazard.
Here are some examples of PPE that should be worn when handling hazardous waste:
Gloves:
Gloves used for handling hazardous materials come in different materials and types, depending on the specific hazard and level of protection required. Here’s a brief description of some of the most commonly used gloves:
Disposable gloves made of latex, vinyl, or nitrile: These gloves are often used for low-risk tasks, such as basic laboratory work, food handling, or housekeeping. They are generally thin and disposable, providing a basic barrier against dirt, dust, and non-hazardous liquids.
Butyl rubber gloves: Butyl rubber gloves are highly resistant to a range of chemicals, including acids, bases, and ketones. They are commonly used in industries such as chemical manufacturing, pharmaceuticals, and laboratory work.
Neoprene gloves: Neoprene gloves are resistant to a range of chemicals, including acids, oils, and solvents. They are often used in industries such as automotive, electronics, and laboratory work.
Viton gloves: Viton gloves are highly resistant to a wide range of chemicals, including strong acids, solvents, and fuels. They are often used in industries such as chemical manufacturing, petroleum refining, and aerospace.
PVC gloves: PVC gloves are resistant to a range of chemicals, including acids, oils, and bases. They are commonly used in industries such as oil and gas, chemical processing, and manufacturing.
Kevlar gloves: Kevlar gloves provide excellent cut and puncture resistance, making them ideal for handling sharp objects or materials. They are commonly used in industries such as metalworking, glass manufacturing, and construction.
It’s important to note that the choice of gloves should be based on the specific hazard and level of protection required, as well as the task being performed. Consult the Material Safety Data Sheet (MSDS) or other relevant documentation for each substance to determine the appropriate gloves required.
Eye protection
Eye protection is an essential part of personal protective equipment (PPE) when handling hazardous waste. There are various types of eye protection available, depending on the type and level of hazard involved. Here are some examples of eye protection used for disposal of hazardous waste:
Safety glasses: Safety glasses provide basic eye protection against impact hazards, such as flying debris or particles. They are typically made of plastic or polycarbonate and can be fitted with side shields for added protection.
Chemical goggles: Chemical goggles provide protection against chemical splashes, vapors, and fumes. They are typically made of plastic or rubber and have a tight-fitting seal around the eyes to prevent hazardous substances from getting in.
Full-face shields: Full-face shields provide protection against impact hazards, chemical splashes, and other airborne hazards. They are typically made of clear plastic or polycarbonate and cover the entire face, including the eyes, nose, and mouth.
Welding shields: Welding shields are used to protect the eyes from the intense light and heat produced during welding operations. They are typically made of tinted glass or plastic and cover the entire face.
Combination eye and face protection: Combination eye and face protection are specialized PPE that provide both eye and face protection against a range of hazards. They may include a combination of safety glasses or goggles and a face shield or welding shield.
Respirators
Respirators are essential personal protective equipment (PPE) when handling hazardous waste. The type of respirator required will depend on the level of airborne contaminants present and the task being performed. Here are some examples of respirators that may be used when handling hazardous waste:
N95 respirators: N95 respirators are a type of air-purifying respirator that filters out at least 95% of airborne particles, including dust, fumes, and microorganisms. They are commonly used for protection against non-oil-based particles in industries such as construction, mining, and healthcare.
Half-face respirators: Half-face respirators cover the nose and mouth and are used for protection against airborne contaminants, such as fumes, gases, and vapors. They typically use replaceable filters to remove the contaminants from the air before it is breathed in.
Full-face respirators: Full-face respirators provide complete coverage of the face and are used for protection against a wide range of airborne contaminants, including hazardous gases and particulates. They typically use replaceable filters to remove the contaminants from the air before it is breathed in.
Powered air-purifying respirators (PAPRs): PAPRs use a battery-powered blower to pull air through a filter, which removes airborne contaminants. The filtered air is then delivered to a mask or helmet worn over the face. PAPRs provide a higher level of protection than air-purifying respirators and are commonly used in industries such as healthcare, pharmaceuticals, and chemical manufacturing.
Self-contained breathing apparatus (SCBA): SCBAs provide the highest level of respiratory protection and are used in situations where the air is immediately dangerous to life and health (IDLH). SCBAs use compressed air to supply breathable air to the wearer and are commonly used in emergency response situations, such as firefighting or hazardous material spills.
It’s important to note that the appropriate respirator required will depend on the specific hazardous waste being handled and the task being performed. Consult the Material Safety Data Sheet (MSDS) or other relevant documentation for each substance to determine the appropriate respirator required. Also, make sure the respirator is properly fitted and used according to the manufacturer’s instructions.
Protective Clothing
Protective clothing, such as coveralls, should be worn when handling hazardous waste to protect skin and clothing from exposure to hazardous substances. Depending on the hazard level, protective clothing can range from disposable coveralls made of polypropylene to more specialized suits made of materials such as Tychem or Saranex.
Disposable coveralls made of polypropylene are lightweight, breathable, and economical. They provide a basic level of protection against dust, dirt, and non-hazardous liquids. These coveralls are usually used for low-risk situations, such as general cleaning or light maintenance work.
Tychem is a brand name for a range of protective suits made of a special fabric that combines a polyethylene film and a nonwoven polypropylene fabric. Tychem suits are more specialized than disposable polypropylene coveralls and are designed to provide a higher level of protection against a range of hazardous substances, including chemicals, biological agents, and particulates. They are commonly used in industries such as chemical manufacturing, pharmaceuticals, and emergency response.
Saranex is a type of fabric that is made of a layer of Saranex plastic film laminated to a substrate of spunbonded olefin. Suits made of Saranex offer a high level of protection against a range of chemicals, including acids, solvents, and pesticides. They are often used in industries such as agriculture, manufacturing, and waste management.
Both Tychem and Saranex suits typically have features such as attached hoods, elasticized cuffs and ankles, and taped seams to provide a better seal against hazardous materials. They are designed to be worn over other protective clothing, such as gloves and respirators, to provide full-body protection.
