Standard Guide for
Generation and Dissipation of Static Electricity in Petroleum
Fuel Systems1

This standard is issued under the fixed designation D 4865; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This guide describes how static electricity may be
generated in petroleum fuel systems, the types of equipment
conducive to charge generation and methods for the safe
dissipation of such charges. This guide is intended to increase
awareness of potential operating problems and hazards resulting from electrostatic charge accumulation.

1.2 This guide is not intended to provide specific solutions
but indicates available techniques the user may wish to
investigate to alleviate electrostatic charges. This guide does
not cover the effects of stray currents or of lightning, either of
which can also produce sparks leading to fires or explosions.

1.3 This guide is not intended to address detailed safety
practices associated with static electricity in petroleum product

1.4 The values in SI units are to be regarded as the standard.
The values in parentheses are for information only.

1.5 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
