Recommended Work Procedures for ATS ChemBond

Recommended Work Procedures for the Use of ATS ChemBond™

Care should be taken to avoid any skin and eye contact with ChemBond™. These procedures are designed to help prevent skin and eye contact.

Note: All personal protective equipment (PPE) must be donned before handling ChemBond™.

Donning Procedures

  1. Chemical resistant long sleeve coveralls should be donned. Examples of acceptable coveralls are TYVEK®/Saranex 23-P, ChemTuff®, or equivalent.
    Note: When heavy usage of ChemBond™ is anticipated, don a nitrile apron over the coveralls to prevent soiling of the coveralls.
  2. Don chemical resistant footwear. Chemical resistant over boots may be worn over personal footwear if desired. All outer footwear should be solvent resistant and have a surface which can be easily cleaned. Open shoes and footwear constructed of porous substances such as canvas and leather are not acceptable when using the raw chemicals.
  3. An inner layer of gloves should be donned and the sleeve of the coverall taped over the edge of the gloves, leaving approximately 2 inches of the glove showing past the wrist. Thin latex and cotton gloves are not acceptable as inner gloves. Inner gloves should be disposable nitrile gloves or equivalent.
    Note: Individuals with a history of dermatitis may apply a layer of an appropriate blocking cream to their hands prior to donning the inner gloves. See part type #583 in the Mechanical Drawing Guide.
  4. Heavy outer elbow length gloves should be placed over the nitrile gloves. Outer gloves should be Silvershield®, Viton®, or equivalent.
  5. Chemical-splash goggles or face shield should be donned prior to commencing work with ChemBond™.

Note: The outer gloves may be removed by using the doffing procedures, as needed. The inner gloves should be changed if they become soiled or torn. The coveralls should be replaced if they become heavily soiled or torn. Use the doffing procedures to remove PPE prior to breaks, lunch and after completion of work for the day.

Doffing Procedures (Removal of Personal Protective Equipment)

Care must be taken during PPE removal procedures so that inner clothing and gloves are not soiled by residue on the outer gloves and coveralls.

  1. Wipe visible residue from the outer gloves, apron and footwear using solvent on a rag. Dispose of the rag as solvent waste.
    Important: Do not use solvent to remove ChemBond™ from the skin. This may lead to dermatitis from exposure to the solvent. Use mild soap and water to remove ChemBond™ from the skin.
  2. Remove the apron and outer footwear and place in an appropriate storage container.Remove the outer gloves by using one hand to loosen the glove on the other hand, and repeat the process with the opposite hand until both gloves are loose enough to fall from the hand. Do not remove the outer glove from one hand and then use the inner glove to remove the outer glove on the opposite hand. This will soil the inner glove.
  3. Remove the tape from the sleeve of the coverall over the inner glove. Remove the coveralls, rolling them in on themselves so that any resin will be on the inside. Dispose of the coveralls in an appropriate container.
  4. Remove the inner gloves and dispose of in an appropriate container.
  5. Remove any personal clothing such us shoes or hats which are soiled with ChemBond™ and leave at the work site. Soiled clothing should not be taken home. It should be cleaned or disposed of at the work site.
  6. If there is any question at all as to procedure, contact the ATS technical staff at (510)234-3173.

The guidelines below are important to follow when using ChemBond™ Resin.

General Precautions

ChemBond™ resin can cause irritation; wear protective skin and eye equipment. Do not heat in bulk: decomposition may occur, releasing fumes.

Specific Personal Protective Equipment

For Inhalation:
Respirators are not needed with ChemBond™ unless the putty/resin is smoking (which can only occur if the ChemBond™ is catalyzed in too much bulk). If the resin is smoking or being atomized, an organic chemical cartridge respirator is needed in non-vented areas.

For Eyes:
Splash-proof chemical goggles

For Skin:
Elbow-length rubber gloves. Shorter latex gloves are not recommended. The use of Blocking Cream (ATS Part type #583) is highly recommended. The Blocking Cream is applied prior to working with the resin and helps prevent allergic reactions.

(1) Appropriate equipment to prevent probability of skin and eye contact (such as Tyvek suits or overalls).

(2) Good general mechanical ventilation and local exhaust.

Special Note

Proper protective clothing should be used during the mixing and installation of ChemBond™ resin. All people inside the immediate work area should wear proper protective clothing. Please review the donning procedures for ChemBond‘ resin use to determine the required protective equipment.

Procedures for removing ChemBond™ resin when spilled on protective clothing:

If proper work procedures are followed no worker will be using ChemBond‘ resin without proper protective clothing. The following procedures are presented in the unlikely event that ChemBond™ resin is spilled on someone not wearing protective clothing.

Procedures for removing ChemBond™ resin spilled on skin or regular clothing:

Warning: If resin comes into contact with the eyes, immediately flush eyes with water. Continue flushing the eyes for at least fifteen (15) minutes with copious amounts of water. Consult a physician as soon as possible.
