INSTRUCTIONS FOR USE

steps should be taken to ensure the wearer of suit is properly earthed. The resistance

between the person and the earth shall be less than 10

footwear.

C to +60

Warnings & Important notes for AlphaTec® AIRline suits

The employer is responsible for ensuring that any person working and using respiratory

equipment is fully informed regarding the correct use of the equipment.

For detailed instructions on the safe-use of the respiratory equipment please refer to the

manufacturer's instructions provided with those items.

It is recommended that prior to use, full training is given on the safe use and limitations

by a competent person, with details of the training recorded. Refer to donning and

doffing instructions supplied with these garments.

• This product should only be used where the risk of damage to the compressed air

supply tube is low and where movement of the wearer is limited.

• The host airline system must be capable of delivering a minimum of 175 litres per

minute and a maximum of 260 litres per minute at a working pressure of between 5

and 7 bar. If the host airline system operates at different pressures then adjustments

should be made to ensure the minimum and maximum flow rates are achieved.

• Check the flow immediately if the visor starts to fog.

• The positive pressure generated in the head-top prevents particles and other

pollutants from entering the breathing zone.

• Low temperature use: underneath the suit wear suitable clothing that provides

adequate warmth for the working environment.

• Air supplied by the airline system must conform to EN 12021:2014 for composition and

permissible upper limit of the following contaminants: Oil, Carbon Dioxide, Carbon

Monoxide and moisture. Do not supply any other gas such as Oxygen, Nitrogen,

Carbon Monoxide, etc. and ensure connection points are properly marked. Use of any

other gas apart from breathing quality air may result in death.

• Ensure that the length of supply hose selected is sufficient for the task being

undertaken. According to EN 14594 the maximum working length of compressed air

supply tubes for Class A devices shall be 10m.

• Air for compressed airline respiratory protection devices must have a dew-point

sufficiently low to prevent condensing and freezing.

• Appropriate checks must be made to ensure that the airline system can deliver the

required flow rates for all users

• Where apparatus is used and stored at a known temperature the pressure dew-point

must be at least 5

C below the likely lowest temperature. Where conditions of use and

storage of the compressed air supply is not known, the pressure dew-point must not

exceed -11

• DO NOT use equipment that is damaged. A monthly inspection of the apparatus is

a mandatory requirement in the UK under COSHH regulations and inspection on a

monthly basis is strongly recommended for all other countries.

• The equipment may not provide adequate protection in certain highly-toxic

atmospheres.

• The protection factor may be reduced if the equipment is used in environments where

high wind speeds occur.

• Never lift or carry the equipment by the breathing hose.

• The suit has been tested according to EN 1073-1 for ventilated protective clothing

against particulate radioactive contamination, however the product is not intended to

protect from radiation.

The equipment must not be used;

• If the suit or airline system are damaged in any way

• If the airline is not running. In this abnormal situation, the equipment will offer

no respiratory protection. In addition there is a risk of carbon dioxide quickly

accumulating in the head top, which would lead to oxygen deficiency

• If the surrounding air does not have a normal oxygen content

• If the pollutants/hazards are unknown

• In environments that are immediately dangerous to life and health (IDLH)

• With oxygen or oxygen enriched air

• If you find it difficult to breathe

• If you can smell or taste the pollutants

• If you experience dizziness, nausea or other discomfort

In the unlikely event of defects, do not wear the garment.

Take care to ensure that the shoe covers are well positioned over your shoes to obtain

the correct contact of the sole to the floor.

Important note: these models are not recommended for applications involving walking

Model 762 also features a semi rigid GAG visor

Donning/Use Procedure

For safety purposes and to ensure proper closure it is suggested to have an assistant

("buddy") to help with the donning and doffing of the suit.

Follow these steps to don the suit correctly and attach the compressed air-supply to the

suit

(FIG. illustrations can be found on page x):

• Having visually inspected the suit for any defects, remove shoes (model 750), empty

your pockets of any items that could hinder you or damage the protective clothing.

Shake the garment out (this makes it easier to put on having been flat packed)

• Fully open the zippers on the suit

• Remove the airline regulator unit and hose carefully from their packaging

• Thread the end of the hose (FIG. A) through the self fabric loops on the rear of the

suit and the opening in the neck seal. Insert the hose into the holder and clamp in

place using the locknut (FIG. B & C)

• Place the airline regulator unit the correct way up inside the suit, within close

proximity of the pass-thru hose tail

• With the suit and airline regulator (inside) laid on a flat surface connect the breathing

hose to the regulator diffuser. (FIG. D & E)

• Pass the compressed airline hose through the hose tail on the suit and connect to the

CEJN fitting on the bottom of the regulator (FIG. F & G)

Donning the suit & Airline System

• Carefully don to your waist ensuring your feet are positioned correctly in the socks by

pushing your toes to the end.

• Follow the airline regulator unit manufacturer instructions to position the waist belt

comfortably and fasten firmly (FIG.H). Turn on the breathing air supply.

• With the help of your dressing assistant, lift the suit up onto shoulders and place your

arms into the sleeves (FIG. I)

• Make sure the breathing hose runs along your back and is not twisted

• Pull the hood of the suit over your head (make sure the breathing air supply is

switched on!) (FIG.J)

• The dressing assistant should close the inner and outer zips (FIG. K & L) remove the

double-sided tape and seal down the storm flap. If necessary and for full liquid &

particle protection the assistant should apply additional adhesive tape over the edges

of the flap. The hood and suit body will now fully inflate (FIG. M & N).

• Don your gloves, placing the outer gloves over the outer sleeve of the coverall and ask

your assistant to seal the cuff to the coverall with self adhesive waterproof tape.

• Using a self adhesive waterproof tape, seal the suit pass-thru hose tail to the

compressed air hose (FIG. O)

Doffing the suit & regulator unit

• Leave the hazardous area before taking the equipment off

• Care should be taken when removing contaminated garments, so as not to

contaminate the user with any hazardous substances. If garments are contaminated

then decontamination procedures should be followed (i.e. decontamination shower)

prior to removal of the garment.

• If the suit has been exposed to hazardous chemicals, exercise proper

decontamination procedures before removing

• Remove the suit by following in reverse order the steps for donning the suit.

• Upon contamination, wear or damage the garment should be removed and disposed

of properly.

Note: The person assisting in the doffing procedure should wear appropriate PPE,

selected by a competent person

Emergency Doffing/Rip-cord

AlphaTec® AIRline suits are supplied with a "tear-off" strip positioned on the left

shoulder as you wear the suit. Under normal conditions this can be used as means of

rapidly doffing the suit. Alternatively the strip can be used in an emergency to enable

rapid doffing.

Grasp the strip with one hand and tear downwards across the chest. Once torn the

fabric can be torn further by using two hands, if necessary.

Remove arms from sleeves, withdraw head from hood, unfasten the suit waist belt and

regulator and lower the suit to the floor. Step carefully out of the suit.

Note: Once the rip-cord has been utilised the suit is no longer operational

Storage – Do not store in excess heat or direct sunlight. Refer to the respiratory device
