Respirator facepieces, cartridges, and filters are routinely counterfeited. Most buyers cannot verify whether what they received is authentic, and the marketplace isn’t set up to ensure authenticity. Respiratory protection is especially vulnerable to counterfeits because the most safety-critical functions cannot be confirmed by visual inspection. A trained eye might catch subtle tells, inconsistent molding marks, off-color materials, or printing and labeling errors. But appearance does not verify performance. You cannot reliably determine by sight whether a cartridge contains the correct sorbent, whether a particulate filter actually meets its required performance rating, or whether facepiece materials and components will maintain a stable seal under real-world conditions over time. A respirator’s protective performance is driven by materials and manufacturing tolerances, including the composition and consistency of the facepiece elastomer, the integrity of the lens and frame, strap and buckle hardware strength and elasticity, sealing surface geometry, and the design and quality of inhalation and exhalation valves. Small substitutions or dimensional changes can materially affect fit, seal reliability, and durability. For filter cartridges, protection depends on the correct filter media or sorbent formulation, a reliable seal between the cartridge and the facepiece, and internal construction that controls airflow distribution and loading. Substitutions in media, sorbent, adhesives, gaskets, or internal geometry can reduce protection immediately and may lead to premature chemical breakthrough or inadequate filtration performance. Because these performance characteristics cannot be confirmed by inspection, the only practical safeguard is a verifiable supply chain. When chain of custody is unclear, the buyer has no defensible basis to trust authenticity, certification, or performance. The risk is highest when products come from online marketplaces like Amazon, especially third-party sellers, liquidators, or “new in box” resellers with no traceable sourcing. Commingled inventory practices, where “identical” products from different sellers can be pooled in warehouses, further increase the risk of counterfeit products entering the supply chain. Despite specifically advising clients not to purchase PPE, especially respirators, from Amazon, eBay, or similar online marketplaces, we are seeing this guidance disregarded. We arrive to fit test respirators that show subtle differences from the authentic 3M products we supply. In multiple cases, those units are ultimately confirmed as counterfeits purchased through the exact sources we advised against. Using price as the primary, or only, selection criterion for a personal protective equipment vendor is irresponsible. The employer owns the consequences of negligence in purchasing. If there’s an exposure incident, an injury, or an audit, “we got it online” or "it had free Prime shipping" is not a defense. Workers notice too. When employees don’t trust the gear, company safety culture quietly collapses. Buy PPE through: - Authorized distributors - Direct from the manufacturer - Established industrial or safety suppliers with traceability

Respirator cartridges for gas or vapor protection have a limited service life. They need to be changed before they become saturated and can no longer purify the air effectively. If an employer is using air-purifying respirators for protection against gases and vapors, Cal/OSHA T8 §5144(d)(3)(C) requires that the employer either: Use a cartridge with an end-of-service-life indicator (ESLI) that provides an indication to the user that the cartridge has reached the end of its service life. Unfortunately, ESLI cartridges are not available for most chemicals. Implement a time-based cartridge changeout schedule. This must be, per Cal/OSHA, “based on objective information or data that will ensure that ... cartridges are changed before the end of their service life. The employer shall describe in the respirator program the information and data relied upon and the basis for the ... cartridge change schedule.” Relying on users to detect the end of the cartridge service life by smell, taste, or irritation of the chemical passing through is not compliant as a primary method for cartridge changeout. It may be used only as a secondary safeguard to the employer's time-based changeout schedule. This is a common mistake: an employer identifies a potential respiratory hazard, buys respirators, and provides fit testing - yet skips the crucial step of a formal, documented hazard assessment and changeout schedule. For gas or vapor exposures, your written program should clearly specify: • The correct respirator type for the task • Appropriate cartridge or combination filter-cartridge • A time-based changeout schedule supported by data Safewest can help develop or review your respirator program, including hazard assessments and cartridge change schedules.

HAZWOPER (Hazardous Waste Operations and Emergency Response) training requirements apply to certain operations involving hazardous waste. These requirements dictate the amount, type and levels of training that employees working with hazardous waste must receive. The requirements for hazwoper training can be found in Cal/OSHA § 5192 and Federal 49 CFR 1910.120 . In general, there are three categories of hazmat operations, and specific training requirements for each. These three categories are hazmat site cleanup, emergency response, and operations at treatment, storage, and disposal facilities. Site Cleanup Cleanup and removal work at sites that have been identified by a government agency (state, federal, or local) as having an accumulation of hazardous substances that creates a threat to the health and safety of individuals or the environment or both. General site workers removing hazmat with potential exposure to hazardous substances and health hazards shall have 40 Hours of Training + 3 Days Supervised Field Experience. General site workers in areas where hazard levels have been fully identified, exposures are below published safety limits, there are no health hazards, no possibility of an emergency release, and respirators are not required shall have 24 hours of training + 1 day supervised field experience. Occasional/limited site workers (such as those doing monitoring or surveying) and are unlikely to be exposed to dangerous levels of hazmat shall have 24 hours of training + 1 day supervised field experience. Supervisors of general site workers shall meet the same training requirements as that category of general site worker, plus have an additional eight additional hours of specialized hazardous waste operations management training. All categories of site cleanup workers shall have 8 hours of annual refresher training. Emergency Response Emergency response to releases of, or substantial threats of releases of, hazardous substances, regardless of location. Awareness Level (FRA): Basic awareness, recognize hazmat threat, call for help. Competence based, no hourly requirement. Operations Level (FRO): Defensive response, contain and limit the release. Competence based, or 8 hours of training required. Hazmat Technicians and Hazmat Specialists: Direct response to stop a release of hazardous substances. Training scope and duties varies depending on position/role. 24 hours of training required. Incident Commander/Manager: Control and manage scene, implement response plans. 24 hours of training required. All emergency response workers shall receive annual refresher training or evaluation to demonstrate competency in their required areas. TSDF Operations Operations at Hazardous Waste Treatment, Storage, and Disposal Facilities (TSDFs) Workers are required to have 24 hours of initial training, and 8 hours annual refresher training.
