Hazard Communication
Hazard Communication (HazCom) is a workplace program aligned with OSHA's GHS standard that ensures workers know which chemicals are present, their hazards, and safe handling through labels, Safety Data Sheets (SDS), and training. It requires chemical information to be available and understandable to employees, covering coolants, adhesives, solvents, and cleaners in manufacturing environments.
In a CNC shop, millwork plant, or edgebanding cell, HazCom governs every chemical used—from soluble coolants and metalworking fluids to solvent-based adhesives and cleaners. The program demands an up-to-date chemical inventory, SDS access at the machine, labeling of secondary containers, and specific training for operators, maintenance staff, and cleanup crews. For example, before an operator tops off a sump or removes sludge, they must recognize the fluid’s dilution requirements, incompatibilities, required PPE, and first-aid steps. During maintenance, technicians opening pumps, changing filters, or flushing lines face chemical exposure from residual fluids, even when the machine is stopped. In millwork, workers applying primers or cleaning rollers need to understand flammability, ventilation, and skin sensitization. HazCom is not just paperwork—it directly prevents mist inhalation, dermatitis, and improper mixing by ensuring that hazard information is available and understood at every point of use.
- Secondary containers go unlabeled: A squirt bottle or tote filled from bulk cleaner lacks a label, so workers cannot identify hazards, leading to wrong PPE or incompatible mixing.
- SDS are not accessible at point of use: The facility has binders somewhere, but operators cannot reach them quickly during a spill or skin exposure, delaying critical response actions.
- Training does not match actual processes: Generic HazCom content is shown, but workers are not taught risks like mist, dermatitis, or solvent vapors specific to their cell, leaving them unprepared for real exposures.
What does HazCom require beyond SDS binders?
A written program, chemical inventory, proper labeling of all containers, SDS access for employees, and training on the hazards and protective measures for the chemicals they actually use.
Why is GHS alignment important in a shop environment?
GHS standardizes labels and SDS so workers can rapidly recognize hazard classes, signal words, pictograms, and precautionary statements across different suppliers, improving safety and compliance.
Does HazCom cover only liquids?
No; it covers all hazardous chemicals used or stored in the workplace, including coolants, solvents, adhesives, cleaners, and related chemical products in manufacturing operations.
