Engineering controls and sound workplace practices are often the first line of defense against diisocyanate exposures, and guidelines have been established to help individuals avoid overexposure and adverse health effects. For example, the Occupational Safety and Health Administration (OSHA) has a Respiratory Protection Program Standard (29 CFR §1910.134) to address respiratory hazards. It is important that employees wear any personal protective equipment (PPE) recommended for their specific job functions. With proper precaution and the use of engineering controls and PPE, a worker can protect himself or herself from overexposure to diisocyanates.
It is important for workers to understand and adhere to safe handling practices for any chemical that poses a health hazard. This may include, but is not limited to, wearing eye protection, gloves, coveralls or lab aprons and respiratory protection.
