Well-site operation, safety equipment

Typically, safety begins with the field personnel. All well-site operations require the use of safety equipment, such as fire-retardant clothing... 

Control of site equipment is always important for safety and operational concerns. Many sites are remote or not staffed on a daily basis. Remediation equipment should be fitted with failsafe systems to shut down the system in the event of failure, fire, or unusual conditions (such as injection well plugging). Alarm systems should be included, which may be as simple as illuminating a warning hght, or as complex as a teleconnection to a remote computer station or telephone alert to the operator s residence. Many commercial companies offer remote monitoring equipment. 

PERSONAL PROTECTION wear impervious protective clothing, including boots, chemical-resistant gloves, lab coat, apron, sleeves, or coveralls wear splash-proof safety goggles or face shield enclose operations and/or use local exhaust ventilation at the site of release explosion-proof electrical equipment is required, as well as non-sparking handtools appropriate respirators are needed in areas where exposure would be above the permissible exposure level in high vapor concentrations, wear self-contained breathing apparatus maintain eyewash baths and safety showers in work area. 

Pb-Free Solders. The equipment types described in the preceding sections are often combined to form an electronics assembly line. The term line implies that the equipment is physically located end to end, thereby allowing for the movement of circuit boards between the different functions or stations. Although this scenario is, in fact, typically the case, it need not always be so. Under some circumstances, it may be advantageous to locate some stations a distance away others on the shop floor, thus requiring operators to move product between the two sites on wheeled racks. This is usually the case with inspection and repair/rework functions as well as for some cleaning processes due to health or safety concerns. The setup and hence the flow of a product assembly process are referred to as the (assembly) line architecture.
