Bump Test

Perform a Bump Test before each day's use to verify proper device operation. Failure to perform this
test can result in serious personal injury or death.
Bump test frequency is often stipulated by national or corporate regulations; however,
bump testing before each day's use is generally the accepted best safety practice and
is therefore MSA's recommendation.
This test quickly confirms that the gas sensors are functioning. Perform a full calibration periodically to
ensure accuracy and immediately if the device fails the Bump Test. The Bump Test can be performed
using the procedure below or automatically using the GALAXY or GALAXY GX2 Test Stand.
CSA requires (per 22.2 NO. 152) that combustible sensor sensitivity be tested before each day's use
on a known concentration of methane equivalent to 25 to 50 % of full scale concentration. ACCURACY
MUST BE WITHIN 0 to +20 % OF ACTUAL. Correct accuracy by performing the calibration procedure
described in chapter 3.10.
NOTE: The Automated Test Stands cannot test the following sensors:
GALAXY
Chlorine Dioxide
% Vol Butane
% Vol Propane
% Vol Methane
For these sensors, use this Bump Test procedure.
