Many hazmat situations are caused by mixing incompatible cleaning chemicals together: Holiday Inn Hotel Evacuated, 13 Treated for Chemical Exposure in Mason City

MAY 31, 2015

(ABC 6 News) -- UPDATE: Emergency crews have left the Holiday Inn hotel. The fire department says they ventilated the hotel this afternoon and the scene is now cleared.

Firefighters say that an employee mixed together two industrial strength cleaning products, on accident, and the mixture created a chlorine-like gas creating respiratory issues for hotel workers.

The toxic reaction sent 13 to the hospital because the toxic vapor spread throughout the building.

EARLIER REPORT:

According to the Mason City Fire Department, the local Holiday Inn Express was evacuated just a few hours ago after some people mixed together two chemicals that created toxic fumes.  

The fire department said six people were sent to the Mercy Medical Center North Iowa to be treated for chemical exposure.

Fire and emergency crews are still at the hotel monitoring situation. 

Investigation is still on going.



Mixing common household cleaning products can cause serious injuries.  This fact sheet describes some of the hazards of mixing chlorine bleach and other common household cleaning products, and a few of the possible health effects. 

 Be sure to always read the product labels before using household or institutional cleaning products.

What is chlorine bleach, and where is it found in the home?

Sodium hypochlorite is the active ingredient in chlorine bleach.  It is found in household bleach and many other disinfectants.  Sodium hypochlorite reacts with ammonia, drain cleaners, and other acids.  Many household products state that they contain bleach on the label.

Pool chemicals frequently contain calcium hypochlorite or sodium hypochlorite, and should not be mixed with household cleaners.
Do not mix bleach and ammonia.
Do not mix bleach and acids.
Do not use two drain cleaners together, or one right after the other.


Where are ammonia and acids found in the home?
Ammonia:
In addition to ammonia purchased as a cleaning product, ammonia may be found in the following:
some glass and window cleaners
urine (be careful if you clean cat litter boxes or use a diaper pail)
some interior and exterior paints.

Acids:
Products containing acids include:
vinegar
some glass and window cleaners
some automatic dishwasher detergents and rinses
some toilet bowl cleaners
some drain cleaners
some lime, calcium and rust removal products
some brick and concrete cleaners

What are the dangers of mixing these common cleaning products?
Mixing bleach and ammonia:
When bleach is mixed with ammonia, toxic gases called chloramines are produced. Exposure to chloramine gases can cause:

coughing
shortness of breath
chest pain
wheezing
nausea
watery eyes
irritation to the throat, nose and eyes
pneumonia and fluid in the lungs

Mixing bleach and acids:
When chlorine bleach is mixed with an acid, chlorine gas is given off. Chlorine gas and water combine to make hydrochloric and hypochlorous acids.

Chlorine gas exposure, even at low levels, almost always irritates the mucous membranes (eyes, throat, and nose), and causes coughing and breathing problems, burning and watery eyes, and a runny nose. Higher levels of exposure can cause chest pain, more severe breathing difficulties, vomiting, pneumonia, and fluid in the lungs. Very high levels can cause death.

Chlorine can be absorbed through the skin, resulting in pain, inflammation, swelling, and blistering. Hydrochloric acid also causes burns to the skin, eyes, nose, throat, mouth and lungs.

Mixing bleach and other cleaning products:
Bleach also reacts with some oven cleaners, hydrogen peroxide, and some insecticides.
