Hazard Messages

Notations appear on pages of this manual to alert the reader to important messages regarding a significant hazard for personnel or equipment. These messages convey three levels of risk as defined below. Failure to observe these instructions can result in death, serious injury, damaged equipment, or loss of product or production.

Operational Safety

The following safety precautions are recommended for all personnel who will operate this equipment.

Operators should immediately report unsafe working conditions to a supervisor.
The operator should understand the function of the entire system including all external devices and equipment that interact with the system.
Before starting operation, the operator should understand the complete task that the system is designed to accomplish.
The operator should know the location and functional status of all devices (switches, sensors, control signals) that can cause the system to move.
The operator should know where each EMERGENCY STOP button is located for both main and external control devices. Do not hesitate to use them in an emergency.
The operator should make sure all safety devices are functioning and periodically checked for proper operation.
The operator should ensure that all personnel are outside the system before starting operation.

Maintenance Safety

The following safety precautions are recommended for all personnel who are responsible for the maintenance or service.

Personnel should ensure that all safety devices are functioning and periodically checked for proper operation before performing maintenance.
Before performing any maintenance, service, or inspection inside the main control, the power source should be turned off and locked out.
Maintenance should be performed on the system with the power OFF. Lockout and tag out procedures should be followed to protect personnel from injury and to indicate the equipment is being serviced.
Place a lock on the main electrical disconnect, as shown below, while performing maintenance.
Personnel should pay careful attention to all devices that may be powered such as motors or pumps.
Release or block all stored energy devices (hydraulic) that may present a danger when working with the system. Before working with fluid devices, shut off the supply and purge the lines.
Use only specified replacement parts. Never use non-specified fuses. Potential fire and/or damage may result.
Before restarting the system, ensure personnel are not in the system and that the system and external devices are operating properly.

Lockout and Tagout

Electrical System (See OSHA 1910.147 & OSHA 1910.333 (b)(2) for exception to procedures) To avoid hazards of electrical shock or other personal injuries, the main power disconnect for the system and any other separate sources of power for the system shall be locked out & tagged as a safety precaution during entry and maintenance to the system.

To accomplish this, set the Main Power Disconnect operating handle to the “OFF” position and install a personal locking device through the padlock hole on the operating handle. Attach a Danger tag to the handle containing a statement prohibiting unauthorized operation of the disconnect and removal of the tag signed by the individual responsible for locking out the system. If several personnel are performing maintenance, everyone shall install a lockout device and tag.

A qualified person shall verify that the equipment is de-energized by:

Operating controls to verify equipment cannot be restarted.
Using test equipment to test circuits and electrical parts that will be exposed to personnel.

Stored electric energy that might endanger personnel shall be released by discharging the circuits. Check appropriate equipment manuals on exact procedures before you re-energize equipment, a qualified person shall conduct tests and visual inspections, as necessary, to verify that all tools, electrical jumpers, shorts, grounds, and other such devices have been removed, so that equipment can be safely energized. Personnel exposed to the hazards associated with re-energizing equipment shall be warned to stay clear of equipment. Each lock and tag shall be removed by the person who applied it or under their direct supervision. A visual determination that all personnel are clear of the equipment shall be accomplished before Main Power is applied.

Fluid Systems

To avoid hazards of pressurized fluids and other personal injuries, the water supply valve and coolant supply hoses for the system shall be locked out & tagged as a safety precaution during entry and maintenance to the main system.

To accomplish this, turn the main supply valve to the “OFF” position and install a personal locking device through the padlock hole on the valve handle. Do the same for the coolant supply hoses.
Also attach a DANGER tag to the handle containing a statement prohibiting unauthorized operation of disconnect and removal of the tag signed by the individual responsible for locking out the system.

If several personnel are performing maintenance, each individual shall install a lockout device and tag. Qualified personnel shall vent any stored or accumulated air in pneumatic/ vacuum devices before working on them. Check appropriate equipment manuals on exact procedures.

To re-supply fluid to the equipment, a qualified person shall conduct visual inspections, as necessary, to verify that mechanisms are properly connected, as well as all tools and other objects have been removed so that equipment can safely operate. Personnel exposed to pneumatic/vacuum hazard areas shall be warned to stay clear of equipment. Each lock and tag shall be removed by the person who applied it, or, under their direct supervision. A visual determination that all personnel are clear of the equipment shall be accomplished before the main supply valve is turned to the “ON” position.
