Equipment & technology
Equipment with a similar name can have different models and operating limits. The 3M 6006K cartridge article covers target substances and restrictions, while the flame arrester explanation distinguishes gas flow from flame propagation.
Identify workplace conditions such as substances, concentration and temperature, then compare them with the instructions for the exact model. Once the principle is clear, check installation, inspection and replacement conditions that govern actual use.
Portable hazardous-location blowers: checking the system from fan to duct outlet
A hazardous-location rating does not determine whether the air is safe. Check power, ducting, airflow and the atmosphere at the work position separately.

Static grounding and bonding: maintaining the path from clamp to earth
Attaching a clamp does not by itself establish a path for dissipating charge. Examine the contact point, monitoring circuit and transfer-stop function separately.
