that may affect safety. A crane must be load tested within the specified time period and have the
boom stenciled, like the forklift. It must also have a serviceable fire extinguisher with a minimum rating
of 1-BC that has an intact seal.
Requirements for a crane operator are the same as those for the forklift operator. The operator must
be qualified and licensed, must perform responsible operation, must wear hearing protection, and must
follow the signals of the ground guide. Hand signals are shown in figure 1-14.
Figure 1-14. Hand Signals for Wrecker Crane.
Before a crane is used in handling ammunition, outriggers will be positioned and secured. Wheels will
be chocked. When large, bulky loads are being handled, guy lines will be used to guide and stabilize
the load. See figure 1-15. When cable slings (figure 1-16) are used to handle ammunition in crane
operations, the hooks on the cable sling will be snap safety hooks only. Slings must also be load tested
within the specified time period. A tag must be attached showing the date of the test, date of next test
due, and load capacity. Personnel will not walk under the boom during crane operations.
