Description

Overview

The MSA SSR 30/100 and MSA SSR 30/100 B are escape breathing apparatuses designed for use in hazardous environments. They provide respiratory protection in emergency situations where oxygen levels may be low or toxic gases may be present.

• Inhalation
  1. Exhalation
  2. Breathing tube with mouthpiece
  3. Heat exchanger
  4. Breathing bag
  5. Pressure relief valve
  6. Waist belt
  7. KO2-canisterNeck strap
  8. Nose clip

The device is contained in an enclosed and sealed sturdy stainless steel container.
The device includes a chemical canister with potassium hyperoxide [KO2], which is required for the regeneration of the exhaled air.
After inflating the breathing bag with the exhalation air the device it is directly ready for use. During the escape, the device supplies the wearer with breathable air which is prepared in the KO2 canister.
SSR 30/100
The device is worn continuously on the belt.
SSR 30/100 B
The device is worn in front of the chest with a special chest harness.

Function

The MSA SSR 30/100 and MSA SSR 30/100 B use compressed air to provide respiratory protection. The compressed air is stored in a cylinder and is released when the user activates the device. The air is then filtered and delivered to the user through a mask. The device supplies the wearer with oxygen which is created from the chemical potassium hyperoxide
[KO2]. In an emergency, the container is opened and the respiratory protection device is taken out. The device has a closed breathing circuit. When in operation, the exhaled air is transferred into the chemical canister with the potassium hyperoxide. The potassium hyperoxide reacts with the humidity and the carbon dioxide of the exhaled air and, at the same time, creates oxygen and heat. The air for inhalation prepared in this way is fed into the breathing bag and is then inhaled again.
The amount of resulting oxygen depends on the intensity of respiration. Increased respiration [more carbon dioxide, more humidity] increases the formation of oxygen or vice versa.
When the device is used for breathing, the KO2 canister warms up, as does the inhalation air, gradu-ally. This is normal and indicates the correct operation of the device.

WARNING: The device must only be opened for use!
Otherwise humidity from the ambient air can penetrate the open device and affect the performance. Used or opened devices must be replaced by new devices.
The end of oxygen supply is indicated by increase of the inhalation resistance.

Marking/Certification

The MSA SSR 30/100 and MSA SSR 30/100 B are certified to EN 13794 K/20/S standards and are marked accordingly. The devices are classified according to EN 13794 and marked with the type [code letter] and nominal duration [minutes]. The type, nominal duration and referenced standard are marked on the device.
The device is marked as follows:

The Declaration of Conformity can be found under the following link: https://MSAsafety.com/DoC

Demonstration and Training Device
The demonstration and training device can be used for demonstration and practise of wearing and breathing without using a chemical canister. The inhalation air is taken from the ambient air and the exhalation air is expelled outside.
The demonstration and training device is comparable in size, weight, external construction, handling and breathing resistance to the emergency use devices.
To distinguish it from the emergency use devices, the demonstration and training device has marked blue.
For the demonstration and training device the breathing air is taken from the ambient atmosphere, i.e. training must be made in environments free from contamination.

Maintenance and Cleaning

Maintenance Instructions
To maintain readiness for use, the device must be inspected regularly, checked for integrity, tightness and, if necessary, cleaned [do not use metal brushes!]. Other maintenance measures are not required. As the device contains a chemical which is sensitive to moisture, it is packed in an airtight container and is sealed at the factory.
The frequency of inspection depends on the device load [chapter 4.4].
For used and/or opened devices, the chemical canister must always be replaced, reuse is not permitted. Internal checks and any repairs to the devies are to be carried out by the MSA Customer Service or authorized service centers.

Return of Used Device
For return of used or opened devices, observe the following:

• Pack the device and components in the device containers only after they have cooled down and are dry.

• No organic substances must enter the chemical canisters [e.g. solvents, oils, etc.].

• Observe transport regulations [chapter 5].
  If the complete device cannot be packed in the container, the following procedure is required:

• Remove the chemical canister from the device:

  • Therefor loosen the clamp and remove the breathing bag and breathing tube.
  • Pack the chemical canister inside the container and seal with the original locking assembly of the container.
  • Do not use finely cutted filling material.

• Place the other components of the device with the closed container in a carefully packed package.

• The components must be complete and undamaged.

Tightness Test
The tightness test of the device is carried out using the MSA tightness tester for chemical oxygen breathing protection apparatus. Detailed descriptions of the structure, function, use and maintenance of the tightness tester can be taken from the relevant operating manual of the tightness tester chapter 8].
The tightness test of the device is carried out as follows:

1. Push the device without any straps into the tightness tester in such a way that the cover points towards the door.
2. Close the door and lock.
3. Set timer to 90 s.
4. Create overpressure with the lever, i.e. push the lever downwards until it engages and start the timer at the same time.
5. After 30 seconds, cover the black pointer with the red pointer.
6. After a further 60 seconds, the timer signals the end of the test period. Then read the pressure difference between the red and the black pointers.

The device is tight if the black pointer remains in the prescribed pressure range and if the pressure difference is no more than 5 mbar.
If the pressure drop is more than 5 mbar, the unit must be replaced.

Maintenance Intervals

WARNING: The product must be inspected per the instructions of this section and removed from service if it does not pass the inspection. Use of product that has not passed inspection may result in
over-pressurization of the product, an ignition danger or other condition thereby seriously compromising the user’s life.

National regulation must be observed, e.g. control interval according German Mining Regulation.
User specific conditions may require shorter intervals.
The service life depends on the type and kind of treatment to which the device were subjected.
The intervals below apply for devices used in a single shift operation of 8 hours during a normal work week of 5 days. Increased use requires the intervals to be shortened. For example, working in a double shift (2 x 8 hours per day and 5 days per week) will reduce the expected lifetime by 50% to 5 years.

1. The intervals are based on the date of manufacture [month/year] on the container. Devices manufactured in the same year are considered as “population” and should be combined for inspection.
2. Perform the tightness check every 6 months for all devices used more than in a single shift operation.
3. Perform a complete check of 2% of the population after 1 year, for devices exposed to high mechanical stress, sustained vibration and/or elevated temperature (e.g. stored next to engines).
4. Tightness test with tightness tester D1118845 or by MSA Customer Service.
5. It is recommended that a service contract with MSA Customer Service is made.
6. If the inventory of devices is less than ten devices the inspection after 3 years is not necessary. A complete inspection of the whole inventory of devices is necessary after 5years.
7. 7 Complete check = Internal inspection and check. The result will decide whether the device can be used further.

Documentation
MSA recommends keeping a file for each device where the serial numbers, the dates of manufacture and the dates and results of the inspections are recorded.

Transport regulations
Chemical oxygen devices are classified as Dangerous Goods under Class 5.1 with the designation and hazard label “5.1, 3356, oxygen generator, chemical”. Regard packing group II.
Undamaged and unopened devices can be transported in the packing material supplied with the device or in a different approved method of packing.
Damaged and/or opened devices should be welded into a plastic bag and packaged as described in chapter 4.1.
Notes concerning the various transport methods can be taken from the EU safety data sheet.

Disposal

The chemical canister contains strong alkaline and oxidizing substances [potassium hydroxide, potas-sium carbonate and potassium hyperoxide].
For disposal local regulations are to be observed.

Technical Data

The actual duration time may deviate from the service time in dependency on the breathing air volume. As such the duration time in relation to a breathing air volume of only 10 l/min [e.g. sitting and waiting for rescue while breathing from the device] extends up to 100 min.
