Function of Signal Distress Day/Night Smoke and Flare
Three layers of flare comp (red) housed in
aluminium liner.
Percussion igniter assy (primer, cambric / celluloid
strip) – extends centrally through filling:
Igniter striker held in safe position by “safety fork” which
engages a groove in outer end of the striker.
A “D” ring is secured through a swivel link to the safety
fork.
D Ring and swivel located immediately beneath the end
cap.
Pull and twist D ring:
This action allows the safety fork to release the striker
from the safe detent which strikes the percussion cap.
Produces flash that ignites the primed cambric and
celluloid strip running centrally through the main filling.
Burning cambric / celluloid strip ignites flare or smoke
composition dependant on which end is activated.
SDDN No1 Mk5 description
Flare/(Smoke) Unit. The flare/(smoke) unit consists of three layers of flare composition (a smoke composition) housed in an aluminium liner. A percussion igniter extends through a central hole in the unit. The igniter’s striker is held in a safe position by a safety fork which engages a groove in the outer end of the striker; a D ring is secured through a swivel link to the safety fork. The D ring and swivel link are located immediately beneath the threaded end cap.

Disperser Oleoresin Capsicum (OC) Stream use/distance/effect duration
Incapacitate an individual within 3.05-3.65 meters of the disperser unit. Effects last 60 mins.
Disperser Oleoresin Capsicum (OC) Stream size
The OC is stored in a 4 oz Individual Riot Control Agent Disperser (IRCAD) Unit.
Disperser Oleoresin Capsicum (OC) Stream effects
Likely physical effects on the target include respiratory and skin irritation, dizziness caused by inhalation, unconsciousness and possible asphyxia.
The formulation of Disperser OC Stream
Each disperser canister contains 100g of formulation with 0.69% of this being OC. Nitrogen @ 120 PSI for dispersion
Propylene Glycol
Capsaicin
Nitrogen
Water
2-Propanol
The Disperser OC Stream should meet the following functional requirements:
Disperser shall dispense at least 15 separate visible bursts, each initiated by the user.
The duration of each momentary burst shall be within 0.75 ± 0.25 sec.
Effective range (for incapacitation) shall be 0.9 – 3.05 m.
Affect a single person target with the 3.05 m effective range. 30 cm (facial) target at a distance of 3.05 m
When filled and pressurized, the disperser shall not leak.
Safety lock or protective cap which prevents the actuator from being accidentally depressed.

The Simulator Groundburst 81mm, Day, Electric description
The Simulator Groundburst 81mm, Day, Electric comprises a sealed, biodegradable cardboard cylinder filled with an inert natural substance (wood flour). An electrically initiated igniter assembly is located within the canister to initiate the burster charge. The Simulator Groundburst 81mm, Day, Electric forms part of the audio/visual effect within the Battle Effects Simulation System (BESS).
Signal Kit Miniflare 16mm warning
Burns at over 2000°C. Unloaded and the flare cartridges until immediately prior to use. Loaded flare launchers are to be pointed in a safe (vertical)direction at all times.
Personnel participating in static range practices (or employed within a radius of 25m of a firing)shall wear Hearing Protection Devices (HPD) appropriately rated to the level of noise anticipated by similar type firearm training.

Primer Percussion no. 68
Signal Smoke Parachutist No 1 Mk 5 Red uses
Primarily used for the enhancement of parachuting displays, but can be used in any situation where a large volume of coloured smoke is required.
Specifically designed for use by parachutists to mark their descent course during training and exhibition displays.
Can also be activated on the ground as a wind indicator for descending parachutists.
