Kalkwasser Hazard

[Guest reeffoto]

I train Hazmat reponse technicians as part of my job and today we did a training senerio where they respond to a HAZMAT incident.  I decided to use Kalkwasser as my spilled product.  When I did some research I found this is some bad stuff and could be very bad if mixed with other chemicals.  I forgot to bring the Chemical book home but I will and post what it says later this week.  I knew it was bad just not this bad, use caution with this stuff.

Ward...man you are a Hazmat guy!

Calcium hydroxide is caustic

 

What is wrong with salt, sugar, or powdered sugar?

 

hehe, must have been all those hours looking at reef sites online in the middle of the night! What did you mix it with?

[Guest reeffoto]

I didn't mix it with anything.  I just used it as a prop and when the students figure out what it is they need to know how to treat it ie will it permiate through the protective equipment they are wearing.  The senerio in the exercise was a suspicious powder.  We respond to those often.  When I researched it there was a list of chemicals that when mixed with will have very bad results.  I'll post what the chem book said tomorrow.

What ever you post, I will transfer into the "kalkwasser"- everything you wanted to know thread that is pinned.  Thanks for looking this up for us.

Ward...you probably have the same in your book...We use the msds sheets a lot to insure we don't get in trouble

Potential Health Effects

----------------------------------

Inhalation:

Causes irritation to the respiratory tract. Symptoms may include coughing,

shortness of breath. Can cause chemical bronchitis.

Ingestion:

Gastric irritant. Ingestion may be followed by severe pain, vomiting,

diarrhea, and collapse. If death does not occur in 24 hours, esophageal

perforation may occur, as evidenced by fall in blood pressure and severe

pain. A narrowing of the esophagus may occur weeks, months, or years

after ingestion, making swallowing difficult.

Skin Contact:

Corrosive. May cause severe burns and blistering, depending on duration

of contact.

Eye Contact:

Corrosive. May produce severe irritation and pain. May induce ulcerations

of the corneal epithelium. Can cause blindness.

Chronic Exposure:

Prolonged or repeated skin contact may produce severe irritation or

dermatitis.

Aggravation of Pre-existing Conditions:

Persons with pre-existing skin problems or impaired respiratory function

may be more susceptible to the effects of this substance.

4. First Aid Measures

Inhalation:

Remove to fresh air. If not breathing, give artificial respiration. If

breathing is difficult, give oxygen. Call a physician immediately.

Ingestion:

DO NOT INDUCE VOMITING. Give large quantities of water. Never

give anything by mouth to an unconscious person. Call a physician

immediately.

Skin Contact:

In case of contact, wipe off excess material from skin then immediately

flush skin with plenty of water for at least 15 minutes. Remove

contaminated clothing and shoes. Wash clothing before reuse. Call a

physician immediately.

Eye Contact:

Immediately flush eyes with gentle but large stream of water for at least 15

minutes, lifting lower and upper eyelids occasionally. Call a physician

immediately.

5. Fire Fighting Measures

Fire:

Not considered to be a fire hazard.

Explosion:

Not considered to be an explosion hazard.

Fire Extinguishing Media:

Use any means suitable for extinguishing surrounding fire.

Special Information:

In the event of a fire, wear full protective clothing and NIOSH-approved

self-contained breathing apparatus with full facepiece operated in the

pressure demand or other positive pressure mode.

6. Accidental Release Measures

Ventilate area of leak or spill. Keep unnecessary and unprotected people

away from area of spill. Wear appropriate personal protective equipment

as specified in Section 8. Spills: Pick up and place in a suitable container

for reclamation or disposal, using a method that does not generate dust.

Do not flush caustic residues to the sewer. Residues from spills can be

diluted with water, neutralized with dilute acid such as acetic, hydrochloric

or sulfuric. Absorb neutralized caustic residue on clay, vermiculite or other

inert substance and package in a suitable container for disposal.

7. Handling and Storage

Keep in a tightly closed container, stored in a cool, dry, ventilated area.

Protect against physical damage. Isolate from incompatible substances.

Containers of this material may be hazardous when empty since they retain

product residues (dust, solids); observe all warnings and precautions listed

for the product.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits:

-OSHA Permissible Exposure Limit (PEL):

15 mg/m3 (total dust), 5 mg/m3 (respirable fraction)

-ACGIH Threshold Limit Value (TLV):

5 mg/m3

Ventilation System:

A system of local and/or general exhaust is recommended to keep

employee exposures below the Airborne Exposure Limits. Local exhaust

ventilation is generally preferred because it can control the emissions of

the contaminant at its source, preventing dispersion of it into the general

work area. Please refer to the ACGIH document, Industrial Ventilation, A

Manual of Recommended Practices, most recent edition, for details.

Personal Respirators (NIOSH Approved):

If the exposure limit is exceeded and engineering controls are not feasible,

a full facepiece particulate respirator (NIOSH type N100 filters) may be

worn for up to 50 times the exposure limit or the maximum use

concentration specified by the appropriate regulatory agency or respirator

supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting fluids.

glycerine, etc.) are present, use a NIOSH type R or P filter. For

emergencies or instances where the exposure levels are not known, use a

full-facepiece positive-pressure, air-supplied respirator. WARNING: Airpurifying

respirators do not protect workers in oxygen-deficient

atmospheres.

Skin Protection:

Wear impervious protective clothing, including boots, gloves, lab coat,

apron or coveralls, as appropriate, to prevent skin contact.

Eye Protection:

Use chemical safety goggles and/or full face shield where dusting or

splashing of solutions is possible. Maintain eye wash fountain and quickdrench

facilities in work area.

[Guest tgallo]

I know first hand how much this stuff hurts, i made a mistake of useing a flexable plastic spoon to scoop some out of the container and it sprung back and hit me in the eyes, all i can say is HOLY MOTHER OF GOD some one help me.

[AquariaUSA]

Done that one before, but I choose a few different words..Holy was one of them Also done a bit of the powder inhalation when mixing it up. Drank gallons of water, spit my brains out...lived to tell about it, so I guess that is good. Being that it is caustic, and has a known carcinogen in it, we stopped using it in the late 90s. Only problem is a lot of chemicals we use have the same issues.

 

Anyone have Kent RxP? Have problems breathing when you use this product?

[Guest reeffoto]

That pretty much covered it Rich.  Saved me the typing.  I think I'll grab a respirator from work and start wearing gloves.  I have never had it burn me but I don't want to get dermititis again.  I already have that on my hands from photo Chemicals.

It stays away but comes back now and then.
