B. DESCENT SPEED: The average speed at which the user will be lowered when using the Rescumatic®
Emergency Escape Device is 3 ft per second (.9m per second).
C. ENVIRONMENTAL HAZARDS: Use of this equipment in areas with environmental hazards may require
additional precautions to prevent injury to the user or damage to the equipment. Hazards may include, but
are not limited to; high heat, caustic chemicals, corrosive environments, high voltage power lines, explosive
or toxic gases, moving machinery, and sharp edges.
D. TRAINING: This equipment must be installed and used by persons trained in its correct application and use.
E. MAXIMUM SYSTEM LENGTH: The maximum length of descent is 1,000 ft (304.8m) (300 ft [91.4m] in
Canada). Special precautions in storing and unwinding the rope are required for all lengths over 250 ft (76.2m).
F.
NUMBER OF USERS: The Rescumatic® Emergency Escape Device is used by one person at a time.
Multiple descents can be performed.
G. BODY SUPPORT: The webbing body support strap provided with the system provides limited support when
descending. For long descents, or if immediate descent is not mandatory, a full body harness is
recommended to help support and provide comfort to the user.

System Requirements
2.1
COMPATIBILITY OF COMPONENTS: DBI/SALA equipment is designed for use with DBI/SALA approved
components and subsystems only. Substitutions or replacements made with non-approved components or
subsystems may jeopardize compatibility of equipment and may effect the safety and reliability of the complete
system.
2.2
COMPATIBILITY OF CONNECTORS: Connectors are considered to be compatible with connecting elements
when they have been designed to work together in such a way that their sizes and shapes do not cause their
gate mechanisms to inadvertently open regardless of how they become oriented. Contact DBI/SALA if you have
any questions about compatibility.
If the connecting element that a snap hook (shown) or carabiner attaches to is undersized or irregular in
shape, a situation could occur where the connecting element applies a force to the gate of the snap hook or
carabiner. This force may cause the gate (of either a self-locking or a non-locking snap hook) to open,
allowing the snap hook or carabiner to disengage from the connecting point.
1. Force is applied to the
snap hook.
2. The gate presses against
the connecting ring.
3. The gate opens allowing the
snap hook to slip off.
