What marking must be displayed on the outside of flammable/combustible liquid storage cabinets?

The marking that must be displayed on the outside of flammable/combustible liquid storage cabinets is "FLAMMABLE-KEEP FIRE AWAY." This designation is crucial for ensuring the safety of lab personnel and the surrounding environment. The presence of this specific warning serves multiple important functions.

Firstly, it clearly communicates the hazardous nature of the contents within the cabinet to anyone approaching. By emphasizing the need to keep fire away, it alerts individuals to the potential dangers associated with flammable materials and encourages them to adopt safe handling practices. This can help prevent accidents that could arise from negligence or unawareness, ultimately reducing the risk of fires and explosions.

Furthermore, the wording of the marking is designed to provide immediate guidance in emergency situations, as it directly specifies actions to take—keeping fire at a distance. This proactive messaging is essential in maintaining a safe laboratory setting, where the presence of flammable liquids requires constant vigilance.

In contrast, other options may not provide the same level of clarity or urgency in communicating the specific risks associated with flammable materials. It's critical that safety markings are unambiguous and instructive, which is why the chosen marking is the standard for such storage.
