Whether you can fill by weight or by volume is determined by which regulations?

• A. Federal safety standards.
• B. Regulations at the local level.
• C. Manufacturer guidelines.
• D. Company policy.

Answer: (B)

Local regulations govern whether you fill propane by weight or by volume. Different cities or counties may adopt different codes or fire regulations that specify one method over the other. Federal safety standards provide broad safety requirements but don’t mandate the exact fill method in every situation, and manufacturer guidelines describe how a specific cylinder should be filled, with company policy supporting consistency but not replacing local law. So, to know which method is allowed in your area, you must check the local authority having jurisdiction and follow their requirements.
