Decontamination Systems

Personal Decontamination Kit

The Personal Decontamination Kit (PDK) has been designed to decontaminate the CW Personal Decontamination Kitcontaminated areas such as exposed body parts, clothing, gloves, overboots, personal weapons, etc. through physical adsorption if persistent CW agents are detected over these surfaces. The PDK consists of three components, viz., PDK-I, PDK-II, and RDP. PDK-I is a pad containing adsorbent powder. The PDK-II contains a puffer bottle with adsorbent powder, while RDP is a pouch that contains tissue papers soaked in a neutral solution of surfactant. PDK-I and PDK-II removes the liquid CW agents by physical adsorption. RDP removes the solid particles including nuclear fallout.

Salient Features

Dimension : 230 mm x 135 mm x 45 mm
Weight : 480 g
Contents
    PDK-I : 4 sachets
    PDK-II : 1 bottle
    RDP : 2 sachets
Shelf-life : 5 yr in factory packed condition

Status : Introduced into the Services and in regular production.

Portable Decontamination Apparatus

Portable Decontamination Apparatus has been designed to spray decontaminating Portable  Decontamination Apparatussolution over the contaminated area, buildings, vehicles (tanks, ships), etc. The apparatus is made of stainless steel with provision for pressurising the vessel by a pump or from a vehicle compressor. A lance with a scrubber, a brush, a scrapper and an adjustable nozzle has been provided for working from a safe distance from the contaminated surface. Scrapper and brush are used to scratch and brush the contaminated paint of metal panels or wherever required so that the decontaminant can reach the contaminant trapped inside the paint. The apparatus can also be used to spray decontaminant as liquid mixtures and slurries.

The apparatus has been provided with a pressure gauge, a shoulder strap for manual handling and brackets for fixing it on a vehicle.

Capacity : 14 l total
: 12 l charge
Operating pressure : 5.5 kg/cm2
Discharge time at 4 kg/cm2 : Not more than 5 min
Leakage : Not more than 1 kg/cm2
Bursting pressure : Not more than 22 kg/cm2
Spray range : 5 m radius

Status : Introduced into the Services and in regular production.

Decontamination Solution

Decontamination Solution (DS-2) is used for external decontamination of small and medium size Decontamination Solutionarms and equipment. DS-2 is a mixture of organic and inorganic bases and methyl cellosolve. It is yellow in colour, which turns brown on storage and is non-corrosive to metal surface. DS-2 can be used by spraying and swabbing methods. However, it is harmful to skin and eyes for which proper care should be taken while handling it.

Salient Features

Viscosity : 6 (relative to water)
pH : 12 (aqueous solution with 20 times dilution)
Shelf-life : 5 yr in factory packed condition

Status: Introduced into the Services and in regular production.

Mobile Decontamination System

The Mobile Decontamination System has been designed and developed for decontamination of Mobile Decontamination Systemterrain, vehicles, personnel and personal equipment. The system is fitted on a TATRA vehicle with cross-country capabilities. The main sub-systems of mobile decontamination system are: pre-wash, chemical wash, postwash. Pre-wash consists of a 3000 l stainless steel water tank and a fast suction pump. A high-pressure jet with a capacity of 3400 lph at 45-50 bar, and a low-pressure jet with a capacity of 900 lph at 5-6 bar and 1600 lph at 10-15 bar have also been provided. The chemical wash system is capable of mixing two powders and two liquids with variable feed rates. It has a 5 l/min slurry emulsion flow rate. The postwash system consists of a high-pressure hot water jet, a hot water shower for personnel, and provision of steam for decontamination of clothing. The subsystems can be simultaneously operated.

Status: Introduced into the Services and in regular production.
