REHIS Hazard Analysis and Critical Control Point (HACCP) Practice Exam

Using chemicals safely in a food setting hinges on following the manufacturer’s instructions. When products are used exactly as intended, the correct dilution, application method, contact time, and required PPE are all respected. This reduces chemical hazards by limiting exposure to workers, preventing harmful residues on surfaces, and avoiding reactions that can occur with improper usage. The instructions also cover storage and disposal, helping prevent leaks, spills, or accidental mixing that could contaminate food or cause dangerous fumes.

Other practices raise risk. Relying on household cleaners in a professional setting isn’t appropriate because they may not be approved for use on food-contact surfaces or in commercial workflows. Storing chemicals next to food creates a clear contamination pathway. Repackaging chemicals into old containers can lead to mislabeling and accidental misuse, increasing the chance of exposure or improper application. Emphasizing correct use per manufacturers’ instructions keeps chemical hazards under control and supports safe cleaning and sanitizing in line with HACCP prerequisites.
