Explosions can occur when these substances come into contact with sparks, ulo ʻo e afi, certain temperatures, or specific air pressures. It is therefore critical to take measures to prevent such explosions.

This highlights the importance of adhering to strict safety standards, especially in industrial environments where fakafepakiʻi materials are present. The use of Class A devices, with their specified maximum surface mafana ʻo e ʻea, is a key strategy in mitigating the risk of explosions. These devices are designed to operate safely within explosive atmospheres by limiting their surface temperatures below the ignition temperatures of the surrounding velangofua ngaahi nāunaú.
The implementation of such safety protocols ensures that operations in hazardous areas remain secure and explosion-free, thereby protecting both personnel and infrastructure.
