What type of liquids require to be electrically interconnected during transfer?

• A. Only Class II liquids
• B. Any Class I liquids
• C. Class III liquids at lower temperatures
• D. Flammable solids

Answer: (B)

The requirement for electrically interconnecting the transfer equipment during the handling of liquids is primarily to prevent static electricity from building up, which can create a fire hazard. Class I liquids are those that have a flashpoint below 100°F (37.8°C) and are considered flammable. The risk related to these liquids necessitates strict safety protocols, including grounding and bonding to ensure that any static charge is adequately dissipated during transfer operations. This precaution is critical because Class I liquids are capable of producing flammable vapors that can ignite in the presence of an ignition source, such as a spark from static electricity. By ensuring that the transfer equipment is electrically interconnected, the risk of static discharge and potential ignition of flammable vapors is significantly minimized, enhancing overall safety during the handling of these hazardous materials.
