HIGH PRESSURE WASHER

PRIMARY USES

1. Heavy-Duty Equipment and Surface Cleaning in Healthcare Facilities
Primary Use: Provides a powerful petrol-driven cleaning machine (7.0HP, 3000 PSI) designed to remove stubborn dirt, grime, oil stains, and biological debris from hard surfaces, medical equipment, and facility exteriors using high-pressure water jets .
How it helps: For the healthcare facility manager and environmental services team, the 3000 PSI pressure delivers exceptional cleaning power for removing heavy biological soiling, algae, mold, and mineral deposits from exterior surfaces such as walkways, building facades, and parking areas . The pressure adjustable function allows operators to select the appropriate intensity for different cleaning tasks, ranging from delicate surfaces to heavily soiled concrete. The self-priming function also permits water intake from a tank or reservoir when mains water supply is unavailable. For the healthcare facility, this means efficient removal of dirt and biological contaminants that can harbor pathogens, support infection prevention and maintaining a professional, hygienic appearance.
2. Portable Cleaning for Community Health Outreach and Mobile Clinics
Primary Use: Offers a portable, petrol-powered cleaning solution for mobile health units, community health outreach programmes, and field clinics, enabling healthcare teams to maintain hygiene standards in remote or underserved areas where mains electricity and water supply may be limited.
How it helps: For the community health coordinator and field clinician, the petrol engine provides independence from electrical outlets, allowing operation in remote locations where grid power is unavailable . The robust petrol engine delivers consistent power for extended periods, supporting thorough cleaning of mobile clinic vehicles, field equipment, and temporary structures . For the patient and healthcare team, this means maintaining hygiene standards even in challenging field conditions, reducing the risk of contamination and infection spread.
3. Decontamination of External Surfaces in Outbreak Situations
Primary Use: Supports infection prevention and control by providing high-pressure water jets for decontamination of external surfaces, such as walkways, vehicle tyres, building exteriors, and temporary structures during infectious disease outbreaks.
How it helps: For the infection prevention and control team, the high pressure (3000 PSI) combined with detergent application capability effectively removes organic matter and biofilms that can harbor pathogens, preparing surfaces for subsequent disinfection . The adjustable pressure feature allows selection of appropriate settings for different surface types . For the healthcare facility, this contributes to comprehensive infection prevention strategies by addressing environmental contamination, particularly during outbreaks of infectious diseases.

SECONDARY USES

1. Cleaning of vehicles and transport equipment: For healthcare fleets, the pressure washer effectively removes dirt, mud, and biological contaminants from ambulance exteriors, patient transport vehicles, and medical equipment trailers.
2. Maintenance of outdoor and landscaping areas: For healthcare facility grounds, the high-pressure water removes algae, moss, and debris from walkways, car parks, patios, and building exteriors, maintaining a safe and professional environment for patients and staff.
3. Preparation of surfaces for maintenance and repair: The pressure washer can be used for stripping paint, removing old coatings, and preparing surfaces for repainting or resealing as part of facility maintenance programmes.

2. FIRST AID MEASURES

  • Carbon monoxide poisoning (headache, dizziness, nausea): Move person to fresh air immediately. If breathing is difficult or symptoms persist, administer oxygen and seek emergency medical attention.
  • High-pressure injection injury: Seek immediate medical attention. Do not treat as a simple cut. The injury may be deeper than it appears and can involve the introduction of water and contaminants into tissues.
  • Eye contact with debris or water: Rinse immediately with plenty of clean, lukewarm water for at least 15 minutes. Seek medical attention if irritation persists.
  • Burn injury (contact with hot surfaces): Cool the burn with cold running water for 20 minutes. Cover with a sterile dressing and seek medical attention for serious burns.
  • Skin contact with petrol: Remove contaminated clothing and wash skin thoroughly with soap and water. If irritation develops, seek medical attention.

3. FIRE FIGHTING MEASURES

  • Flammability: Petrol is highly flammable. Fuel tank containing petrol will burn if exposed to open flame or spark.
  • Extinguishing Media: Use dry chemical powder, carbon dioxide (CO₂), or foam for fires. Use water spray for cooling surrounding materials. Do not use water on electrical fires.
  • Fire Response: If the pressure washer catches fire, evacuate the area immediately. If it is safe to do so, turn off the fuel supply. Use appropriate extinguisher for the fire type. Call emergency services.
