Know facility safe procedures
Most facilities have internal procedures and rules regarding safe practices within the facility. Be aware of
these safe practices and incorporate them into your daily operation of the system.
Know controls
Before you operate the system for the first time, make a trial run through the operating procedures with the
power off. Locate all hardware and software controls and know what their functions are and what adjustments
they require. If any control function or operating adjustment is not clear, review the applicable information
until you understand it thoroughly.
Know Specimen Properties
The user is responsible for understanding the characteristics of the test specimen. Be sure to use appropriate
personal protective equipment (for example: clothing, hand gloves, eye protection).
Use protective guards such as cages, enclosures, and special laboratory layouts when you work with hazardous
test specimens (for example, brittle or fragmenting materials or materials that are internally pressurized).
Have first aid available
Accidents can happen even when you are careful. Arrange your operator schedules so that a properly trained
person is always close by to render first aid. In addition, ensure that local emergency contact information is
posted clearly and in sight of the system operator.
Be aware of component movement with hydraulics off
The actuator rod can also drift down when hydraulics are turned off hitting anything in its path. This
uncommanded movement is because of oil movement between the pressure/return ports and oil blow by
across the piston hub. Be aware that this can happen and clear the area around the actuator rod when
hydraulics are turned off.
Keep bystanders safely away
Keep bystanders at a safe distance from all equipment. Never allow bystanders to touch specimens or
equipment while the test is running.
Wear proper clothing
Do not wear neckties, shop aprons, loose clothing or jewelry, or long hair that could get caught in equipment
and result in an injury. Remove loose clothing or jewelry and restrain long hair.
Remove flammable fluids
Remove flammable fluids from their containers or from components before you install the container or
component. If desired, you can replace the flammable fluid with a non-flammable fluid to maintain the proper
proportion of weight and balance.
