DOT 49 CFR Section § 192.353 Customer Meters and Regulators: Location

Each meter and service regulator, whether inside or outside a building, must be installed in a readily accessible location and protected from corrosion and other damage, including, vehicular damage that may be anticipated. However, the upstream regulator in a series may be buried.

Each service regulator installed within a building must be located as near as practical to the point of service line entrance.

Each meter installed within a building must be located in a ventilated place and not less than 3’ from any source of ignition or heat.

Where feasible, the upstream regulator in a series must be located outside the building, unless located in a separate metering or regulating building.

This gas standard provides guidelines and instructions for

selecting and installing new and retrofitted gas meter

guards for residential and commercial meters subject to

vehicular traffic

These meter guards are designed to protect against

incidental bump damage during typical low-speed

maneuvering

Type 1 Locations -

Residential

Within 3’ of the following:

A single-family driveway/parking area

A roadway, street, alley, or driveway

with a curb

Within 8’ of the following:

A roadway, street, alley, or driveway

without a curb

A multi-family driveway/parking area

Type 2 Locations -

Commercial

Within 3’ of the following:

A commercial refuse container

location

Within 8’ of the following:

A commercial or industrial

driveway/parking area

A loading dock/freight handling area

Physical protection must be provided for any

gas meter set located in one of the areas

described below:

If a risk of vehicular damage exists at a location,

the meter should be protected by barrier posts:

When field conditions do not permit exact compliance with these

requirements, alternatives may be proposed. Alternative meter guard

arrangements must sufficiently protect the meter set and ensure

adequate distance for maintenance and meter reading.

Residential areas require a minimum 2” diameter Schedule 40 (0.154” thickness) steel post.

Commercial and industrial areas require a concrete-filled, minimum 4” diameter Schedule 40 (0.237” thickness) steel post.
