Emergency Overview
Non-toxic, non explosive and is not a fire hazard.

Eyes
Dust may irritate the eyes from mechanical abrasion causing watering and redness.

Skin
Dust may cause irritation of the skin from friction but cannot be absorbed through intact skin.

Ingestion
Unlikely under normal conditions of use, but swallowing the dust from this product may result in irritation to the mouth and gastrointestinal tract.

Inhalation
Dust may cause irritation of the nose, throat, and airways, resulting in coughing and sneezing. Certain susceptible individuals may experience wheezing (spasms of the bronchial airways) on inhaling dust during sanding or sawing operations.
 

Eyes
Remove contact lens. Flush with running water or saline for at least 15 minutes. Seek medical attention if redness persists or if visual changes occur.

Skin
Wash with mild soap and water. Contact physician if irritation persists or later develops.

Ingestion
If ingested, dilute by drinking large amounts of water. Do not induce vomiting. Seek medical attention.
If unconscious, loosen tight clothing and lay the person on his / her side. Give nothing by mouth to an individual who is not alert and conscious. Seek medical attention.

Inhalation
Remove to fresh air. If shortness of breath or wheezing develops, seek medical attention.

Cutting Outdoors:
1.OCM Building Products recommends positioning cutting station so that wind will blow dust away from user or others in working area and allow for ample dust dissipation.         
2.Use one of the following methods based on the required cutting rate and jobsite conditions. --Best
● Score and snap using carbide-tipped scoring knife or utility knife (Ability to use this method depends on thickness of OCM Board being installed.)
● Fiber cement board shears (electric or pneumatic).--Better
● Dust reducing circular saw equipped with appropriate blade and HEPA vacuum extraction. --Good (for low to moderate cutting only)
● Dust reducing circular saw with appropriate saw blade.
 Always use correct tools when executing all cutting operations.

Ventilation
Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limit.

Respiratory Protection
Dust mask is recommended. 
 

Eye Protection
When cutting material, dust resistant safety goggles / glasses should be worn 

Skin Protection
Loose comfortable clothing should be worn. OCM Building Products recommends that direct skin contact with dust and debris be avoided when possible by wearing long sleeved shirts and long trousers, a cap or hat, and gloves. 

Sanding / Drilling / Other Machining
If sanding, drilling, or other machining is conducted, OCM Building Products recommends wear a NIOSH-approved dust mask.

Important Notes
1. For maximum protection (lowest respirable dust production), OCM Building Products recommends always using “Best” level cutting methods where feasible.
2. Always use a circular saw blade that is appropriate for the specific operation being undertaken. 
3. It is not recommended that a grinder or continuous rim diamond blade be used for cutting.
4. Always follow tool manufacturer’s safety recommendations.
