Product Name: Chiquibul River Water Sample
Synonyms: Surface Freshwater Sample
Recommended Use: Environmental Monitoring, Ecological Assessment
Supplier: Chiquibul Forest Reserve Research Team, Cayo District, Belize
Emergency Contact: Ministry of Sustainable Development, Belize, +501-822-2360
Physical State: Liquid
GHS Classification: Not classified as hazardous under GHS guidelines
Primary Hazards: Potential biological contamination (bacteria, protozoa), possible presence of agricultural runoff (nitrates, phosphates), risk of skin or eye irritation, accidental ingestion risks for sensitive groups
Signal Word: No standardized signal word assigned
Hazard Statements: Contains microorganisms which can cause disease if ingested, high organic load can lower dissolved oxygen in confined spaces, may trigger allergic reactions in susceptible persons
Precautionary Statements: Avoid contact with eyes and open wounds, do not ingest, wear gloves during sampling or testing
Water: 95–99%
Silts and Suspended Solids: 0.2–2%
Organic Matter (including decaying vegetation): 0.1–1%
Microorganisms: Includes bacteria (E. coli, coliforms), parasites (Giardia, Cryptosporidium)
Trace Inorganic Ions: Nitrate (0.1–10 mg/L), Phosphate (0.01–2 mg/L), Calcium, Magnesium
Pesticide Residues: Intermittent, related to upstream agricultural activity
Dissolved Metals: Potential trace levels of iron, manganese, zinc
Eye Contact: Rinse gently with plenty of clean water for at least 15 minutes, remove contacts if present, seek attention if irritation persists
Skin Contact: Wash exposed skin with soap and clean water, treat irritation or rash with appropriate topical treatment
Inhalation: Unlikely exposure; remove to fresh air if symptoms such as coughing or nausea develop after aerosol exposure
Ingestion: Rinse mouth, do not induce vomiting, seek medical advice if symptoms such as diarrhea, fever, or cramps arise
Suitable Extinguishing Media: Water is the substance; not flammable, use standard methods to address combustibles nearby
Specific Hazards Arising: No risk of ignition or explosive reaction from the water sample; organic material may produce minor smoke if concentrated and dried
Protective Equipment: Use standard protective gear for fighting adjacent fires, no special gear required for Chiquibul water sample
Special Procedures: Prevent contaminated runoff from entering municipal drainage during fire suppression
Personal Precautions: Wear gloves and boots to limit exposure to pathogens or contaminants, avoid touching face
Environmental Precautions: Prevent additional water sample from returning to drinking water sources
Containment: Use absorbent materials (sand, earth) for large spills in laboratory or storage zones
Clean-up Methods: Collect and dispose via treated wastewater system or through authorized laboratory waste channels
Handling: Use gloves and eye protection when collecting or analyzing, avoid ingestion, prevent rubbing eyes during work
Storage: Store collected samples in sealed, labeled containers at 4°C or below, avoid freeze-thaw cycles which may disrupt analysis
Incompatibilities: Do not store near strong acids or bases, do not allow contact with foodstuffs
Other Precautions: Handle with awareness that river water may change constitution based on season and rainfall
Engineering Controls: Use fume hood or well-ventilated lab for analysis, maintain clean benches
Personal Protection: Nitrile or latex gloves, splash-resistant goggles, lab coat
Hygiene Measures: Wash hands and face thoroughly after handling, avoid eating or drinking in sample processing areas
Physical Appearance: Cloudy to clear liquid, may have suspended solids
Odor: Earthy, may vary with organic content
pH: Ranges from 6.2–7.4
Melting Point/Freezing Point: 0°C
Boiling Point: 100°C
Solubility: Miscible with water, all constituents dispersed
Density: Approx. 1.0 g/cm³
Vapor Pressure: Similar to water
Evaporation Rate: Comparable with pure water
Chemical Stability: Stable under standard lab storage, subject to decomposition by bacteria beyond 48 hours at room temperature
Conditions to Avoid: Heat, direct sunlight, storage for extended periods
Incompatible Materials: Strong acids, bases, oxidizers
Hazardous Decomposition Products: Methane, hydrogen sulfide, carbon dioxide produced by breakdown of organic matter under anaerobic conditions
Acute Effects: GI symptoms (nausea, vomiting, diarrhea) possible from microbial content
Chronic Effects: Extended exposure or ingestion can result in waterborne illnesses such as giardiasis, cryptosporidiosis, or bacterial infections
Routes of Exposure: Ingestion, skin contact, eye contact
Sensitization: Rare, but allergic responses possible in highly sensitive individuals
Carcinogenicity: Not classified as carcinogenic
Mutagenicity: Not identified for natural river samples
Ecotoxicity: High organic loads may deplete oxygen if added to a closed aquatic system, excess nutrients (nitrates, phosphates) promote algal blooms downstream
Persistence and Degradability: Organic content readily broken down by microbes, chemicals diluted under natural conditions
Bioaccumulative Potential: Limited, though pesticides and metals can accumulate in aquatic food webs
Mobility in Soil: Waterborne contaminants can migrate with groundwater
Other Adverse Effects: Untreated runoff impacts amphibian and invertebrate populations, affects drinking water for communities downstream
Disposal Methods: Small quantities through municipal wastewater system after treatment, large samples via treatment plant or biological digesters
Container Disposal: Decontaminate and recycle sample bottles as per lab protocol
Precautions: Avoid direct release into drinking water supplies or natural waterways, especially if from contaminated or polluted sites
UN Number: Not regulated
Transport Hazard Class: Not classified as dangerous goods
Packing Group: Not applicable
Precautions for Transport: Securely closed containers, cool conditions, clear sample labeling
Special Transport Measures: Notify receiving facility in advance for potentially contaminated samples
International Regulations: Not covered under GHS or ADR for hazardous substances
Local Regulations: Belize Environmental Protection Act applies to field sampling and water quality testing
Labelling Requirements: Clear sample labelling for date, time, origin, and preservation methods
Workplace Safety Standards: Follow local laboratory safety and biosafety procedures for handling natural water samples
