Beta is a measure of an investment's relative volatility. The higher the beta, the more sharply the value of the investment can be expected to fluctuate in relation to a market index. For example, Standard & Poor's 500 Index (S&P 500) has a beta coefficient (or base) of 1.
In the USA, NFPA 1 requires portable fire extinguishers to be mounted with their top no more than 5 feet from the floor, if under 40 pounds, no more than 3 1/2 feet (42 inches) if they are over 40 pounds.

NFPA 1: 13.6.8.1.3.8 (2009), with reference to NFPA 10: 6.1.3.8.
