1.5.1.2 Built to endure the most extreme operating environments, the MSD900’s revolutionary three-layer
modular system is a result of Mustang’s ongoing commitment to research and development.
Crewmembers may use the MSD900 when operating in conditions requiring dry suit use. The
MSD900 is designed for more industrial applications such as aids to navigation maintenance,
buoy deck operations, fisheries boardings and other applications where damage to the suit is likely
to occur.
Protection1.5.2
1.5.3
1.5.4
1.5.2.1 Mustang’s patented breathable closed cell (PVC) foam not only aids in the moisture management
system, but it also provides inherent buoyancy and the basis for hypothermia protection, even in
the event of damage to the suit.
Comfort
1.5.3.1 The Thermal Liner is constructed of our patented breathable closed-cell foam. The Thermal Liner
is engineered with multiple apertures, then quilted using wicking fabrics, designed to pull excess
moisture vapor (sweat) away from the wearer’s body.
1.5.3.2 The Immersion Module uses GORE-TEX®fabric, designed to allow the escape of excess moisture
vapor while providing a waterproof barrier to the outside elements. Adjustable wrist and neck seals
aid in the system’s delivery of superior comfort and flexibility, reducing heat stress and fatigue
associated with long or strenuous operations.
Durability
1.5.4.1 The MSD900’s Outer Shell is constructed of 210-denier nylon and reinforced in high abrasion
areas with even more rugged 500-denier Cordura®nylon panels.

polyurethane/polycarbonate-coated nylon stretch material and is closed via an adjustable, elastic
drawstring system that effectively seals water outside the module and allows personnel to wear
the suit comfortably. The module is fitted with waterproof socks.
1.5.5.4 The third module is the Outer Shell. The Outer Shell is an orange/black, black urethane-coated
nylon shell, which provides a durable water-resistant barrier to wind, sea spray and rain. This
module is vented allowing the suit to breathe. The knee and seat portions of the Outer Shell are
reinforced. An integral foam-lined hood provides protection both in and out of the water.
NOTE: Appropriate thermal undergarments (such as
polypropylene underwear) should be worn
to enhance the protection afforded by the MSD900 and assist in wicking moisture
away from the body.

2.0 IMMERSION AND ANTI-EXPOSURE CLOTHING
2.1 HAZARDS
2.1.1 Cold-water immersion is a life-threatening situation, and your survival depends on the clothing you
wear. Cold, shock, hypothermia, loss of dexterity and mental sharpness and drowning are your
primary concerns. Many strong swimmers drown within yards of safety in cold water. This
suggests that many drown as a result of the rapid shock of immersion, causing immediate
hyperventilation, water ingestion, and often heart failure, which may occur in water below 59ºF
(15ºC).
2.1.2 Without adequate buoyancy and insulation, individuals rely on swimming ability and endurance for
survival. Your strength and endurance are seriously diminished in colder water, reducing your
ability to overcome waves, currents, spray, etc.
2.1.3 Hypothermia results when your body loses heat faster than it can be replaced, and can occur in
any environment below 98.6ºF (37ºC), our normal body core temperature. Water conducts heat
away from our body 25-30 times faster than air, presenting a high risk.
2.1.4 Shivering is the body’s way of generating heat to replace the heat that is lost. The smallest blood
vessels constrict close to the skin, reducing the blood circulation to your hands and feet.
Circulation to the body core is also restricted, where it is needed most, resulting in a loss of
dexterity. As the effect of cold increases, muscles weaken and stiffen, leading to the loss of feeling
and reduced co-ordination. Your decision-making and thinking processes slow down.
2.1.5 Proper clothing reduces many of these hazards, improving your chances of survival. Clothing
should provide insulation from the cold and should not hinder mobility. Ensure buoyancy is
provided either inherently in your outfit, or with an additional life preserver, preferably both.
2.1.6 Generally there are two types of immersion protective clothing:
a. Wet suits
b. Dry suits
2.2 WET SUITS
2.2.1 Wet suits allow some water in, but restrict water movement into and out of the suit. Your body
heats up the water that becomes, more or less, trapped in the suit. If the openings of the suit
become restricted, the warmed water stays inside the suit longer, reducing heat loss. If a wet suit
is damaged or torn, the level of protection is reduced.
2.3 DRY SUITS
2.3.1 Dry suits protect you during cold-water immersion by using, in conjunction with garments worn
under the suit, the trapped air as an insulation layer from the cold water. Most dry suits utilize
seals at the wrists, neck and ankles, unless incorporating gloves and boots. These seals are made
from waterproof materials, insulated or non-insulated.

3.1.2
3.2.1
3.2.2
3.2.3
Familiarize yourself with all the features of the suit to maximize its effectiveness. Illustrations are
provided as an additional reference.
The suit is made of watertight fabric and has neoprene wrist seals and an adjustable neck seal, a
main entry waterproof zipper and a waterproof relief zipper. The suit is watertight and is intended
to keep the wearer dry in the event of immersion. Multiple pockets are included for convenient
storage.
3.2 HYPOTHERMIA PROTECTION
Immersion in cold water is a danger for anyone working on or near the water. The length of time a
person can survive in cold water largely depends on both the water’s temperature and the thermal
protection of their protective clothing.
To create the most effective protection against hypothermia, Mustang Survival begins by
evaluating the clothing’s immersed Clo value, which depicts the level of thermal insulation a
garment provides. Clo is a measurement of insulation, much like the ‘R’ values assigned to
fiberglass house insulation. We determine the rate at which heat is lost from the body, as well as
the difference in temperature between the skin and the water.
Figure 3 indicates random samples of Immersed Clo values and the corresponding estimation of
survival time in cold water (assuming a thin person with a 5.5ºF (3º C) drop in body core
temperature).

3.5.1 Neck and Wrist Seals
3.5.1.1 The adjustable neck and neoprene wrist seals (located on the Immersion Module) are elastic,
allowing the user to stretch each seal over their head or hand and are watertight.
3.5.2 Main Entry Zipper
3.5.2.1 The main entry zipper, located on the Immersion Module (see figure 4), is a heavy-duty zipper with
nickel-silver teeth that provides a watertight seal when closed and wraps around the upper torso.
3.5.2.2 The main entry zipper starts on the front of the suit, under the left armpit, and extends around the
back to the front under the right armpit. A nylon thong is attached to the zipper slider, assisting the
wearer in opening and closing the zipper.
CAUTION: Avoid snagging your clothing in the zipper, as this may break the zipper’s seal.
3.5.2.3 The zippers should always be left in the closed position while the suit is stored. See section 6.5.5
for zipper care procedures and for recommended zipper cleaners and lubricants.
3.5.3 Relief Zipper
3.5.3.1 The relief zipper (see figure 4) is black, with metal teeth and provides a watertight seal when fully
closed. It is located on the front of the MSD900 Industrial Immersion Work Suit and extends
horizontally across the groin area.
3.5.3.2 The zipper closes right to left, from the wearer’s point of view. A nylon thong is attached to the
zipper slider, assisting the wearer in opening and closing the zipper.
