HC R290 Refrigerant Lssues
Basics
HC R-290 (propane) is an odourless and colourless gas of the group of hydrocarbons.
HC R-290 is heavier than air and at high concentrations can cause
narcotic effects and eventually asphyxiation.
R-290 is highly ammable within the range of 2,1% and 9,5% by volume, or 38
g/m3 to 170 g/m3 in air. The auto-ignition temperature is about 470°C.
Since R-290 is an odourless and colourless gas, it is difcult to perceive that it is
present (as with most other refrigerants).
Propane is often used as a fuel such as for heating or barbecues. However, for
use on refrigeration systems, fuel-grade propane is not suitable since it contains
high levels of impurities, which would damage the refrigeration system and may
not provide the desired refrigerating capacity or efciency.
Please notice that the unit is filled with propane. Details to this refrigerant are found in chapter “refrigerant”. Propane is highly
ammable and leads to explosion under certain conditions. Inappropriate treatment of the unit involves the risk of severe damages
of people and material.
The structural formula of HC R-290 (propane)
HC R-290 refrig-
erant has a high
grade of purity.
Propane as a
cooking gas is
not useful for
refrigeration
purpose!

Flammability
Safety Data
Hazard Identication
Three components are needed simultaneously for causing re:
For ignition, the concentration of HC in air has to be between the lower and upper
ammable limits. If the concentration is below the lower ammability limit (LFL) of about
2% by volume in air, there is not enough HC for combustion. If the concentration is
above the upper ammability limit (UFL) of about 10% there is insufcient oxygen for
combustion.
Possible ignition sources are:
1. A flame, for example from brazing torch, halide torch leak lamp, match or
lighter, cigarette
2. A spark from an electrical component
3. Static electricity
4. Hot surfaces
·Extremely ammable (F+).
·Readily forms an explosive air-vapour mixture at ambient temperatures.
·Vapour is heavier than air and may travel to remote sources of ignition (e.g.
along drainage systems, into basements etc).
·Liquid releases generate large volumes of ammable vapour (approx 250:1)
·Cold burns (frostbite) will result from skin / eye contact with liquid.
·Liquid release or vapour pressure jets present a risk of serious damage to
the eyes.
·Abuse involving inhalation of high concentrations of vapour, even for short
periods, which can produce unconsciousness or may prove fatal. Inhalation
may cause irritation to the nose and throat, headache, nausea, vomiting,
dizziness and drowsiness. In poorly ventilated areas unconsciousness or
asphyxiation may result.

First Aid Measures
Fire Fighting Measures
Extinguishing Media:
DO NOT USE WATER JET
Inhalation:
Remove the affected person to fresh air. If breathing has stopped, administer
articial respiration. Give external cardiac massage if necessary. If the person is
breathing but unconscious, place them in the recovery position. Obtain medical
assistance immediately.
Skin:
In case of cold burns: ush with water to normalize temperature. Cover the burns
with sterile dressings Do not use ointments or powders. Obtain medical assistance
immediately.
Eyes:
Cold burns should be ushed with water to normalise temperature, cover the eye
with a sterile dressing and obtain medical assistance immediately.
HC R-290 is delivered, stored, and used at temperatures above their ash point. Avoid all naked ames, sparks, cigarettes
etc.
·In case of re, immediately alert re brigade
·Ensure an escape path is always available from any re
·If gas has ignited do not attempt to extinguish but stop gas ow and allowto burn out.
·Use water spray to cool heat-exposed containers, and to protect surroundingareas and personnel effecting the shut off
·Every precaution must be taken to keep containers cool to avoid the possibilityof a boiling liquid expanding vapour
explosion (BLEVE)
In case of a large re:
Release must be stopped and container cooled by water spray.
Water mist should be used to assist approach to the source of the re.
Large res should only be handled by Fire Brigade.
Small re:
Use dry powder extinguisher

8Technical Information
Service Manual
DO NOT USE WATER JET
Special protective equipment for re ghters:

Note: vapour may collectin conned spaces.
Further actions:
·Stop release
·Use dry powder or carbon dioxide extinguishers
·Cool containers exposed to re by using water / mist spray.
Due to the flammability of R-290 and the risk of fire or explosion during servicing,
special safety rules must be followed during operation. In order to avoid damage for
people and property, particular requirements are listed hereafter.
Before servicing the unit, the surrounding area were the work will be done must be
clear of safety hazards to ensure safe working. Nevertheless it is required to carry out
a risk assessment in order to minimise the risk of ignition of R-290.
1. Any employees and other present persons must be informed about the service and the way the service is done, rst.
2. It is recommended to isolate the working environment in order to keep out any unauthorised personnel.
3. It is useful to set up signs such as „no smoking“ or „access denied“.
4. It is prohibited to store any combustible goods within the working environment.
5. Within two (2) metres radius, ignition sources are not allowed in the working area.
6. Fire extinguisher (dry powder) must be easily accessible at any time.
7. During service work, proper ventilation of the environment must be ensured.
Accidental Release Measures
Accidental Release Measures
The following safety measures must be followed:

Service Manual
Sign plate to protect and mark the working area.
Appropriate detectors, suitable for hydrocarbons, must be available and operational all the time. Appropriate tools and
appliances must be available and ready for operation.
Any employees need to be instructed extensively about the safety measures and the possible safety hazard.
The HC leak de-
tector is indeed
a Personal
Protective
Equipment
(PPE)
device!
While servicing the unit it is recommended for the whole period of work — before,during
and after — to monitor the gas concentration in the air within the work environment. By
monitoring the air within the work environment the danger of a possible formation of
ammable atmosphere can be detected early.
Doing the monitoring, ensure that the gas detectors are suitable for hydrocarbon detection.
Never use open re or a device with an ignition source for the detection of gas or for leak
detection.
Gas Detection
The HC leak de-
tector is indeed
a PPE device!
Before operation of the gas detector the instruction manual must be read carefully. In case of
any questions refer to the detector manufacturer. Furthermore ensure the detector is correctly
calibrated. Instructions for calibration can be found in the instruction manual of the detector or
upon request from the manufacturer.
A possible re-calibration must be done within an area which is free of refrigerants.
In case of a positive detection by the detector any work must be stopped immediately. Any
open ames or ignition sources must be extinguished or removed. In addition to a suitable and
approved HC gas detectors, portable gas detectors can be used.
Such a detector can be clipped to clothing or placed on the floor within the working area.
It should be switched on for the duration of the work, and set to alarm at 15% of the lower
flammability level (LFL), to warn that flammable concentration may be nearby. In this way,
technicians can be alerted whenever an inadvertent release of ammable refrigerant occurs,
and can immediately act upon the relevant emergency procedures.
