Main risks

• Accidental inhalation of dust or aerosols during sampling, especially in environments with potentially harmful particles.
• Cross-contamination when moving the equipment and its accessories between dirty and clean areas.
• Exposure to internal light/laser sources if the equipment is opened or optical ports are handled.
• Electrical hazard, overheating or fire when charging batteries or using unsuitable adaptors.
• Damage due to ingress of liquids, condensation, or coarse dust obstructing the air intake.
• Falls, knocks or trips due to poorly positioned cables, hoses or tripods.
• Incorrect readings from use outside the recommended conditions, which may lead to unsafe decisions.
• Ignition risk if used near flammable gases, vapours or combustible dust.

Safe use

• Avoid bringing the air intake close to the face and place it in a well-ventilated, stable area, away from sources of heat, sparks and flames.
• Do not open the casing or look into optical windows or chambers; keep the air inlet and outlet free of obstructions.
• In areas with potentially hazardous dust, use appropriate respiratory protection and minimise agitation of the material.
• Direct the air outlet towards a safe area; if the equipment has an exhaust filter, install it correctly.
• Manage cables, hoses and stands so they do not obstruct walkways, and avoid tugs or the equipment falling over.
• Do not use the counter in rain, dense fog or with visible condensation unless it is specifically protected for such use.
• Use only compatible chargers and batteries; charge on non-flammable surfaces and avoid covering the equipment during charging.
• Before important measurements, perform the basic checks indicated by the manufacturer (e.g., filter condition, connections and flow rate).

Storage and maintenance

• Store the equipment clean and dry, in its case or in a place protected from impacts, dust, moisture and direct sunlight.
• Clean the exterior with a slightly damp cloth; do not use solvents, direct pressurised air at the intake, or sharp objects.
• Check and, if appropriate, replace filters, hoses and accessories when they are dirty, damaged or saturated.
• Between dirty and clean locations, disassemble and clean or replace the necessary accessories to avoid cross-contamination.
• Periodically check the condition of the battery and connections; do not use swollen, damaged or leaking batteries.
• Avoid storing in vehicles or areas with extreme temperatures; if not used for a long time, leave the battery partially charged.
• Follow the verification and calibration schedule recommended by the manufacturer to maintain the reliability of measurements.

Usage restrictions

• It is not a medical device or an alarm system; do not use it as the sole criterion for critical safety or health decisions.
• Do not use in potentially explosive atmospheres or in the presence of flammable gases, vapours or combustible dust unless the equipment is specifically designed for this.
• Do not insert probes into ducts with fans running or onto hot surfaces without appropriate safety measures.
• Do not use the equipment to sample corrosive gases, concentrated solvent vapours, very hot smoke or environments with heavy condensation.
• Do not modify the equipment or use incompatible accessories; do not cover or block the ventilation, inlet or outlet openings.
• Not suitable for children; use should be by people familiar with the basic operation of the equipment and its working environment.
