Safety Precautions
Hazardous Locations
The Sigma 900 MAX Refrigerated Sampler is not approved for use in
hazardous locations as defined in the National Electrical Code.
DANGER
Although some Sigma products
are designed and certified for
installation in hazardous
locations as defined by the
National Electrical Code, many
Sigma products are not suitable
for use in hazardous locations. It
is the responsibility of the
individuals who are installing the
products in hazardous locations
to determine the acceptability of
the product for the environment.
Additionally, to ensure safety, the
installation of instrumentation in
hazardous locations must be per
the manufacturer's control
drawing specifications. Any
modification to the
instrumentation or the
installation is not recommended
and may result in life threatening
injury and/or damage to facilities. DANGER
Bien que certains produits Sigma soient conçus et certifiés pour être installés
dans des endroits dangereux tels que définis par le National Electric Code, de
nombreux produits Sigma ne conviennent pas pour de tels endroits. Il relève de
la responsabilité des personnes qui placent les produits dans des endroits
dangereux de déterminer s'ils sont adaptés à cet environnement. En outre, à des
fins de sécurité, le placement de machines dans des endroits dangereux doit
s'effectuer dans le respect des consignes des schémas de contrôle du fabricant.
Toute modification apportée aux machines ou tout déplacement de celles-ci est
déconseillé, car susceptible de provoquer des accidents matériels et/ou
corporels.
Confined Space Entry
Important Note: The following
information is provided to guide
users of samplers on the dangers
and risks associated with entry into
confined spaces. On April 15, 1993, OSHA's final ruling on CFR 1910.146, Permit Required
Confined Spaces, became law. This new standard directly affects more than
250,000 industrial sites in the United States and was created to protect the
health and safety of workers in confined spaces.
Definition of Confined Space
A Confined Space is any location or enclosure that presents or has the
immediate potential to present one or more of the following conditions:
• An atmosphere with less than 19.5% or greater than 23.5% oxygen
and/or more than 10 ppm Hydrogen Sulfide (H
2
S)
• An atmosphere that may be flammable or explosive due to gases, vapors,
mists, dusts, or fibers
• Toxic materials which upon contact or inhalation, could result in injury,
impairment of health, or death
Confined spaces are not designed for human occupancy. They have restricted
entry and contain known or potential hazards. Examples of confined spaces
include manholes, stacks, pipes, vats, switch vaults, and other similar
locations.
Standard safety procedures must always be followed prior to entry into
confined spaces and/or locations where hazardous gases, vapors, mists,
dusts, or fibers may be present. Before entering any confined space check
with your employer for procedures related to confined space entry
