1-4 Safety
SAFETY AND HEALTH HAZARDS
Although the DektakXT system has been designed with safety in mind, it does contain some inherent
potential hazards. Physical hazards associated with operating the equipment are discussed in this
section.
Mechanical Hazards
Mechanical hazards exist in the systems wherever moving parts are located, such as slides. Protection
against most of the mechanical hazards in the DektakXT system is provided in the form of a hood and
system base. Wherever possible, physical guards have been placed around moving parts to prevent
personnel from contacting them. The exceptions are the areas around and above the X-Y stage. These
areas, however, do not contain pinch-point hazards.
Some maintenance tasks may require removal of the hood and system base. In these cases, safe work
practices, including use of lockout procedures for electricity, pressure (pneumatic system) or other
applicable hazards, should be followed. Only trained service personnel should perform maintenance
activities that require mechanical motion while the hood and base are removed.
Pressure Hazards
Pressure hazards exist due to the difference in kinetic energy of a gas within a container or piping
system and the surrounding environment. If a sudden breach of a gas line or a pressurized container
were to occur (for example, a gas delivery line bursts), the pressure differential between the gas in the
line and the surrounding atmosphere will cause the gas to be forcefully expelled into the surrounding
atmosphere. This can cause physical injuries due to particles flying outward with extremely high
speed.
The DektakXT system uses compressed clean dry air (CDA) to operate the optional vibration
isolation table. It is designed to use CDA at the typical house-supplied pressures of 50 psi. The CDA
fittings or components of the pneumatic system should be adjusted only after appropriate release of
air-line pressure. As with electrical and mechanical tasks, maintenance activities involving the air
lines should occur only after appropriate pressure lockout procedures have been implemented (see
General Lockout/Tagout Procedures in the section that follows).
INSTALLATION AND MAINTENANCE SAFETY ISSUES
Certain installation activities require attention to special safety hazards in addition to the overall
system hazards discussed in the
Safety and Health Hazards section above. The installation of the
systems requires connection and adjustment of electricity and pressurized air lines. These types of
activities require knowledge and use of lockout/tagout procedures.
Maintenance procedures often present greater hazards to personnel than normal production activities
due to the need to defeat safety features in order to access the equipment. The following sections
present general information on some of the key safety-related procedures or actions that maintenance
personnel should follow when servicing the DektakXT system.
