Chemical Composition & Hazardous Ingredients
Detailed component analysis, concentration ranges, and hazardous substance identification
Product Type
mixtureGeneral Composition
Wood ash is a highly variable material whose composition depends on wood source/mix, combustion type and conditions, amount and composition of any tramp soil material, mixture of different ash streams, solids size distribution and degree of wetting before shipment. Final composition and form can affect health and physical hazards. Although wood ash residual is often wetted before shipment and is also hydrophilic, water was not included in the ingredients as it may evaporate.
Chemical Components & Hazardous Substances
| Chemical Name | CAS Number | Concentration | Hazardous |
|---|---|---|---|
| Wood Char (incompletely burned wood material containing residual Carbon) | N/A | 5-50% | ✓ Non-hazardous |
| Silica (amorphous, non-crystalline) | 7631-86-9 | 1-10% | ✓ Non-hazardous |
| Silica (crystalline, quartz) | 14808-60-7 | 0.1-1% | ✓ Non-hazardous |
| Aluminum Oxide | 1344-28-1 | 1-10% | ✓ Non-hazardous |
| Calcium Oxide | 1305-78-8 | 30-70% | ✓ Non-hazardous |
| Iron Oxide | 1309-37-1 | 1-5% | ✓ Non-hazardous |
| Magnesium Oxide | 1309-48-4 | 5-10% | ✓ Non-hazardous |
| Manganese | 7439-96-5 | 0.1-1% | ✓ Non-hazardous |
| Potassium Hydroxide (and other potassium compounds such as potassium oxide K2O) | 1310-58-3 | 10-30% | ✓ Non-hazardous |
| Sodium Hydroxide (and other sodium compounds) | 1310-73-2 | 1-5% | ✓ Non-hazardous |
Composition Notes
* Wood char and ash may contain trace (ppt levels) amounts of dioxin compounds; the non-metallic portion in the char can contain variable but significant residual carbon content which can affect dust combustibility. The non-char portion of the material is true ash from more completely combusted wood containing metals and their oxides. Common names:[1] Limestone;[2] burnt lime, quicklime[3] potash;[4] alumina;[ 5] ferric oxide;[6] magnesia.[**] Oxide compounds’ presence, oxide and hydroxide combinations and corresponding concentrations will vary depending on source and combustion conditions. Some oxides may also exist as their metal carbonates (e.g., calcium carbonate) although the oxides are expected to predominate. *** Silica in its quartz form may be present if tramp soil material carries over into the combustion process.
Emergency First Aid Measures
Critical first aid procedures for chemical exposure incidents and medical emergencies
🫁 Inhalation Exposure
If inhaled, remove person to fresh air and keep comfortable for breathing. Get medical attention if breathing difficulties do not quickly resolve or if exposure was extensive.
Symptoms:
breathing difficulties, respiratory irritation, unpleasant obstruction to the nasal passages, nosebleed, chemical irritation, and possible corrosive burns to the membranes of the upper respiratory tract.
🖐️ Skin Contact
If on skin or hair, rinse off using water or otherwise remove immediately (vacuum, gentle brushing), take off contaminated clothing and wash before reuse.
Symptoms:
irritation and corrosive burns. As the material becomes wet on contact with moisture such as sweat, it can form a corrosive liquid and cause burning and corrosive damage of the skin depending on concentration and degree of contact. Airborne wood ash can settle on exposed skin and may cause irritation and corrosive burns. Causes skin irritation and possibly corrosive type burns. Prolonged direct contact inside boots and gloves can exacerbate skin damage and lead to ulceration.
👁️ Eye Contact
If in eyes, rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
Symptoms:
irritation and corrosive burns to the eyes. As the material becomes wet on contact with moisture such as the eye surface, it can form a corrosive liquid and cause burning and corrosive damage of the eyes depending on concentration and degree of contact.
🍽️ Ingestion/Swallowing
Rinse mouth and do not induce vomiting.
Symptoms:
severe irritation and burning of the mouth and digestive tract.
🚨 Immediate Medical Attention Required
Get medical attention if breathing difficulties do not quickly resolve or if exposure was extensive (for inhalation). Medical evaluation is recommended if symptoms persist or if exposure was extensive (for eye contact). Obtain medical attention for signs or symptoms of persisting skin irritation or any skin damage (for skin contact).

Exposure Controls & Personal Protective Equipment (PPE)
Occupational exposure limits, engineering controls, and required safety equipment
🏭 Engineering Controls
LOCAL EXHAUST – Provide local exhaust as needed so that exposure limits are met. Ensure that combustible dust aspect is investigated if enclosed systems including conveyors are used to capture and convey ash dust. MECHANICAL (GENERAL) – Provide general ventilation in processing and storage areas so that exposure limits are met. SPECIAL – Material may clog ventilation systems, requiring ongoing inspection and cleaning. Other Engineering Controls: NAP
🧤 Hand Protection
Cloth, canvas, or leather gloves are recommended when handling the dry product to minimize potential mechanical irritation. If product becomes wet, neoprene, butyl, or nitrile gloves are recommended. Ensure glove interior is kept clean. Discard gloves with contaminated interiors.
👁️ Eye Protection
An emergency eye wash fountain should be present near areas of potential eye exposure. Goggles or safety glasses are recommended when handling this product.
😷 Respiratory Protection
Use NIOSH-approved filtering face piece respirator (“dust mask”) or higher level of respiratory protection as indicated and goggles where ventilation is not possible and exposure limits may be exceeded or for additional worker comfort or symptom relief. Following a determination of risk from potential exposures, use respiratory protection in accordance with requirements such as US-OSHA respiratory protection standard 29CFR 1910.134.
🦺 Skin/Body Protection
An emergency shower should be present near areas where extensive skin contact is possible. Protective clothing with long sleeves or disposable outer garments may be desirable in extremely dusty areas.
Chemical Stability & Reactivity Data
Chemical stability, hazardous reactions, and incompatible materials information
⚗️ Reactivity
Depending on concentration and degree of hydration of any Calcium Oxide, heat may be generated from the chemical reaction of CaO and water. Depending on amount and concentration, significant heat buildup may occur when calcium oxide initially reacts with water.
⚠️ Hazardous Reactions
May occur
🚫 Conditions to Avoid
Avoid open flames. Depending on dryness, particle size, airborne concentration, and amount of residual combustible material (carbon) material, ignition of a dust cloud may occur if sufficient static energy is applied.
🧪 Incompatible Materials
oxidizing agents and strong acids
💨 Hazardous Decomposition Products
Carbon monoxide and carbon dioxide.
