Key Principles
Several accidents (burn wounds) with serious
consequences are recorded each year due to contact with
hot condensate or exposure to steam
Hazard posed by steam and hot condensate should be
identified and the risk reduced using systems already in
place in all units, such as Last Minute Risk Assessment,
Work Permit, etc.

What is dangerous about overheated steam?
Special Note: Overheated Steam
Answer: It’s very hot and you can't see it!!!

Why Is Hot Condensate Dangerous?
We worry about hot hydrocarbons / chemicals and additives but
condensate is only water !

Why Is Hot Condensate Dangerous?
Burn wounds start to develop when
there is contact with temperatures as
low as 140 °F (60 °C)
3 barg steam is already 248 °F
(120 °C)
40 barg steam is 716 °F (380 °C)

(Data from American Burn Association)
The degree (1st, 2nd of 3rd) of burn
wounds depends on temperature,
duration of contact and energy
capacity of the product that causes
the burn.
So contact with steam often results in burn wounds even though PPE
may be worn

Why Is Hot Condensate Dangerous?
Steam traps contain condensed steam often at 194 °F (90 °C) and always above 167 °F (75 °C) - so the potential for burn wounds is always present.
Hot condensate has a greater (energy) capacity to cause burn wounds than steam.

Equipment / Location Where The Contact Is
Possible
Atmospheric condensate drums
Steam drums
Atmospheric exhausts from
turbines or other equipment
Silencers from turbines of other
equipment
Steam traps

Equipment / Location Where The Contact Is
Possible Condensate drains used for winterizing
Excessive draining or leakage can result in pools of hot condensate
accumulating at grade and filling holes, sumps, low points, etc.
……and more (add yours)
Locations where hot condensate is being temporarily discharged / drained
Locations where equipment is being purged with steam
Uninsulated sections or damaged insulated sections of:
– Steam lines
– Condensate lines
– Steam tracing

Precautions To Prevent Contact
If it is necessary to discharge hot condensate to an open system, the following precautions can be taken:
Guide the hot condensate to an area not normally occupied by
people.
Barricade / segregate the area if possible.
Place signs to alert personnel and communicate the hazard to
affected personnel.
Remark the hazard in work permits and LMRA
Steam hoses should be properly secured when used for routing the
condensate.
Hot condensate should not be discharged in locations where light
hydrocarbons and high vapor pressure chemicals (flammables or
dangerous to health or simply bad smelling) might be present to
avoid excessive evaporation

Winterizing is of special concern:
– Release of hot condensate is increased
Precautions To Prevent Contact
Special precautions are necessary when:
– Commissioning steam tracing
– Troubleshooting steam trap and tracing
failures
– Draining accumulations of hot condensate
– Discharging steam to atmosphere

Steam traps might temporarily plug; the pressure build- up
can result in a sudden / violent release of hot condensate
with potential for splashing in the surroundings
Precautions To Prevent Contact
Burns and Hot Condensate

Steam is used to heat hydrocarbons and
chemicals:
– Insulation for protection against accidental
contact with hot piping and surfaces is done
only where presence of personnel is routine.
– Viscous hydrocarbons and chemicals will
adhere to fabric and skin:
• The severity of burn wounds might increase due
to the prolonged heat transfer
• Do not attempt to remove the product adhering to
skin to avoid tearing the skin

How To Protect Yourself
Know where the risks are on your unit(s).
Make sure steam and condensate systems on your unit(s)
are well maintained.
Make sure that steam trap drain / tail lines are tied down so
that they cannot injure someone when they discharge.
When preparing work in the field or practicing LMRA before
start of work, check for location of steam traps and
discharge direction vs yourself.
Be on the lookout for new hazards that are caused by steam
and condensate as the units are being prepared for winter
operations.
Know what to do if you are burned and the location of safety
showers. At first, flush with a lot of (normal temperature)
water for at least 15 minutes. Quick response may minimize
the severity of the burn.

Burns: Memory Refresher
Burns can be caused by dry heat (like fire), wet heat (such
as steam or hot liquids), radiation, friction, heated objects,
electricity, or chemicals.
Thermal burns are the most common type. Thermal burns
occur when hot metals, scalding liquids, steam, or flames
come in contact with your skin.

Burns: Memory Refresher
Burns to your airways can be caused by inhaling smoke, steam,
superheated air, or toxic fumes, often in a poorly ventilated space

Burns: Memory Refresher
There are three levels of burns:
First-degree burns affect only the outer layer of the skin. They cause
pain, redness, and swelling.
Second-degree (partial thickness) burns affect both the outer and
underlying layer of skin. They cause pain, redness, swelling, and
blistering.
Third-degree (full thickness) burns extend into deeper tissues. They
cause white or blackened, charred skin that may be numb.

First Aid - For Minor Burns
If the skin is unbroken, run cool water over the area of the burn or soak it in a cool water bath (not ice water).
Keep the area submerged for at least 5 minutes.
A clean, cold, wet towel will also help reduce pain.
Calm and reassure the person.
Burns and Hot Condensate

After flushing or soaking, cover the burn with a dry, sterile
bandage or clean dressing.
First Aid - For Minor Burns
Protect the burn from pressure and friction.
Once the skin has cooled, moisturizing lotion also can help.

Minor burns will usually heal without further treatment.
First Aid - For Minor Burns
However, if a second-degree burn covers an area more than 2 to 3 inches in diameter, or if it is located on the hands, feet, face, groin, buttocks, or a major joint, treat the burn as a major burn.
Do not take any medicine (other than pain reliever if required) without seeking medical attention
Burns and Hot Condensate

Call site or local medical emergency
immediately
First Aid - For Major Burns
DO NOT remove burnt clothing or
product that is stuck to the skin.
DO NOT apply any ointments. Avoid
breaking burn blisters.
Make sure the person is breathing. If
breathing has stopped, or if the
person's airway is blocked, open the
airway. If necessary a trained person
can begin rescue breathing and CPR.
Burns and Hot Condensate

Cover the burn area with a dry sterile bandage (if available) or clean cloth. A sheet will do if the burned area is large.
First Aid - For Major Burns
If fingers or toes have been burned, separate them with dry, sterile, non-adhesive dressings.
Elevate the body part that is burned above the level of the heart. Protect the burnt area from pressure and friction.
Take steps to prevent shock. Lay the person flat (but NOT if a head, neck, back, or leg injury is suspected) elevate the feet about 12 inches, and cover with a coat or blanket. Continue to monitor the person's vital signs until medical help arrives.
