It is important to identify hazards that are specific to prosthetic labs. For each hazard identified, the Personal Protective Equipment required is discussed. The following hazards are covered in this module: Common Chemicals, Dust, Heat, and Noise.
In this module, PPE for each hazard is identified. It should be understood that: Appropriate PPE should be worn at all times when at your work station PPE should be properly fitted and in good condition. PPE should be regularly cleaned and should not impede vision or breathing. PPE alone will not prevent injury. Good judgment, good housekeeping, and good hygiene must be maintained at all times.
Styrene An ingredient in many laminating resins Breathing high levels can cause tiredness, muscle weakness, depression, and nausea. It can also cause eye, throat, and nose irritation. Styrene is considered a carcinogen
Acetone Used as a solvent in prosthetic labs Moderate to high levels can cause eye, nose, throat, and skin irritation. It can also cause lightheadedness, confusion, nausea, and confusion. In pregnant women, organic solvents have been related to fetal malformation and increased rate of miscarriage.
Toluene An ingredient in contact cement and glues Low to moderate levels from long-term exposure can cause tiredness, confusion, weakness, memory loss, nausea and loss of appetite. Inhaling a high level of toluene in a short time can make you feel light headed, dizzy, or sleepy.
Toluene (cont.) Toluene can cause neurologic problems and retarded development in babies if the mother inhales a high level of toluene during pregnancy
Isopropyl Alcohol A solvent used for cleaning adhesive and silicone Can cause irritation after contact with eyes, skin, nose, and throat Overexposure can cause drowsiness, headache, dizziness, and loss of coordination
Methy ethyl Ketones An ingredient in contact cement and glues Can cause irritation of nose, throat, and eyes. Serious effects are seen at very high levels of exposure.
Bisphenol A (BPA) Ingredient in the epoxy resin in the 5 minute epoxy Can cause eye, skin, respiratory tract irritation Overexposure can cause headaches, nausea, dizziness
Epoxy Hardener (trade secret) Hardener ingredient in 5 minute epoxy Can cause severe irritation of eyes, mouth, nose, throat, and respiratory tract.

According to air quality testing conducted on January 15, 2011, a formal respiratory program is not required at Evolution Industries. This means that we will provide you with an particulate mask if you request it, but it is not required in this workplace. In fact, you may not wear a half facepiece or full facepiece when a voluntary program is in place since it may impede your breathing.
Because a respiratory program is not required at Evolution, use of a mask is voluntary when grinding or sanding: 3M 8511 Particulate Respirator N95 with Valve, NIOSH approved. N95 means it is not resistant to oil and filters 95% of airborne particles. These masks are disposable particulate respirators. After approximately 8 hours of use they can be discarded for reasons or hygiene or damage.
Carbon Fiber Dust When cut or sanded, carbon fiber can cause skin and respiratory irritation and contact dermatitis.
An N95 particulate mask may be worn to protect against respiratory irritation. Gloves, long sleeves, and lab coats are helpful to protect exposed skin from dust. Safety glasses are provided to protect the eyes, especially when cutting or grinding.
According to the noise level testing conducted on January 15, 2011 an auditory conservation program is not required at Evolution Industries. This means that we will provide you with hearing protection if you request it, but it is not required in this workplace.
Ovens used to heat plastic for thermoforming are set to 350 – 400 degrees Heat from oven racks or metal frames can cause burns to hands and forearms.
Thermal gloves are provided that cover the hands and wrists Kevlar sleeves are provided for use when gloves and the employees’ clothing together do not cover the arms.
