ACGIH Threshold Limit Values (TLV)8.2 Exposure ControlsAppropriate Engineering ControlsA laboratory fumehood or other appropriate form of local exhaust ventilation should be used to avoid exposure.Personal Protective EquipmentAll recommendations below are advisory in nature and a risk assessment should be performed by the employer/enduser prior to use of this product. The type of protective equipment must be selected based on the amount andconcentration of the dangerous material being used in the workplace.Eye/Face ProtectionSafety goggles or face shield. All equipment should have been tested and approved under appropriate standards, suchas NIOSH (US), CSA (Canada), or EN 166 (EU).Skin ProtectionGloves should be used when handling this material. Gloves are to be inspected prior to use. Contaminated gloves areto be removed using proper glove removal technique so that the outer surface of the glove does not contact bare skin.Dispose of contaminated gloves after use in compliance with good laboratory practices and local requirements.Gloves used for incidental exposures (splash protection) should be designated as “chemical resistant” by EU standardEN 374 with the resistance codes corresponding to the anticipated use of the material. Unrated gloves are notrecommended.Suggested gloves: AnsellPro Sol-Vex nitrile gloves style 37-175, 15 mil thickness.Penetration time has not been determined.Gloves used for prolonged direct exposure (immersion) should be designated “chemical resistant” as per EN 734 withthe resistance codes corresponding to the anticipated use of the material.Suggested gloves: AnsellPro Viton/Butyl gloves style 38-612, 4/8 mil thickness.Penetration time has not been determined.These recommendations may not apply if the material is mixed with any other chemical, or dissolved into a solution.

risk assessment must be performed to ensure the gloves will still offer acceptable protection.Body ProtectionFire resistant (Nomex) lab coat or coveralls.Respiratory ProtectionRecommended respirators are NIOSH-approved N100 or CEN-approved FFP3 particulate respirators. These are to beonly used as a backup to local exhaust ventilation or other engineering controls. If the respirator is the only means ofprotection, a full-face supplied air respirator must be used.9.
