Consolidated 1982 Series Safety Relief Valve Manual | 2

Proper installation and start-up is essential to the safe and reliable

operation of all valve products. The relevant procedures recommended by

Baker Hughes, and described in these instructions, are effective methods

of performing the required tasks.

It is important to note that these instructions contain various “safety

messages” which should be carefully read in order to minimize the risk

of personal injury, and/or the possibility that improper procedures will be

followed which may damage the involved Baker Hughes product, or render

it unsafe. It is also important to understand that these “safety messages”

are not exhaustive. Baker Hughes can not possibly know, evaluate, and

advise any customer of all of the conceivable ways in which tasks might

be performed, or of the possible hazardous consequences of each

way. Consequently, Baker Hughes has not undertaken any such broad

evaluation and, thus, anyone who uses a procedure and/or tool, which

is not recommended by Baker Hughes, or deviates from Baker Hughes

recommendations, must be thoroughly satisfied that neither personal

safety, nor valve safety, will be jeopardized by the procedure and/or tools

selected. If not so satisfied, contact your local Green Tag Center (GTC) if

there are any questions relative to procedures and/or tools.

The installation and start-up of valves and valve products may involve

proximity to fluids at extremely high pressure and/or temperature.

Consequently, every precaution should be taken to prevent injury to

personnel during the performance of any procedure. These precautions

should consist of, but are not limited to, ear drum protection, eye protection,

and the use of protective clothing, (i.e., gloves, etc.) when personnel are in,

or around, a valve work area.

It is the responsibility of the purchaser or user of Baker Hughes valves/

equipment to adequately train all personnel who will be working with the

involved product. For more information on training schedules, please

contact your local Green Tag Center (GTC). Prior to working with the

involved valves/equipment, personnel who are to perform such work should

become thoroughly familiar with the contents of these instructions.

Wear necessary

protective equipment

to prevent

possible injury.

II. Safety Notice

III. Product Safety Sign and Label System

If and when required, appropriate safety labels have been included in

the rectangular margin blocks throughout this manual. Safety labels

are vertically oriented rectangles as shown in the representative

examples (below), consisting of three panels encircled by a narrow

border. The panels can contain four messages which communicate:

• The level of potential harm from the hazard

• The nature of the hazard

• The consequence of human and/or product interaction with the

hazard.

• The instructions, if necessary, on how to avoid the hazard.

The top panel of the format contains a signal word (DANGER,

WARNING, CAUTION or ATTENTION) which communicates the level

of potential harm from the hazard.

The center panel contains a pictorial which communicates the nature

of the hazard, and the possible consequence of human and/or product

interaction with the hazard. In some instances of risk to human health

and safety the pictorial may, instead, depict what preventive measures

to take, such as wearing wearing the appropriate personal protective

equipment (PPE).

The bottom panel may contain instructions on how to avoid the hazard.

If there is a risk to human health and safety this message may also

contain a more precise definition of the hazard, and the consequences

of human and/or product interaction with the hazard, than can be

communicated solely by the pictorial.
