Visual Inspection

Structural Firefighting / Electrical

Visual Inspections / Assessments are done by a team of experienced engineers and professionals trained well to judge the most critical areas and to collect the required information’s

Knowledge and Experience

Visual inspection is one of the most versatile and powerful of the NDT methods, and it is typically one of the first steps in the evaluation. Visual inspection can provide a wealth of information that may lead to positive identification of the cause of observed distress. Its effectiveness depends on the knowledge and experience of the investigator, broad knowledge in structural engineering, materials, and construction methods is needed to extract the most information from visual inspection

Why to do Structural Visual Inspections

  • Sizes of structure elements to check and verify (Span/depth ratios)
  • Cracks appearance and its intensity observations
  • Detection of non-engineered structures
  • Concrete spalling, peeling or dampness and its causes detection
  • Distressed structural elements due to overloading
  • Unsafe roof / floor (with no or inadequate parapet / railings)
  • New opening penetrations in slabs / walls without safety measures
  • Unstable high cantilever walls
  • Precast roof members adequacy checks
  • Availability of lateral bracings in steel sheds / warehouse
  • Adequacy checks of steel to steel, steel to concrete connections
  • Feasibility of carrying loads
  • Deterioration, corrosion, rusting of structural members
  • Identify location to perform further NDT and destructive testing
  • Identify structural defects causes and their onward solutions
  • Structural Inspections during Construction Stage
  • Fire Damaged Warehouses / Steel Sheds Inspections for Insurance companies
  • Structural Pre-Purchase Inspections

Why to do Firefighting Visual Inspections

  • To check each extinguisher if it is correctly located in the designated place.
  • Each extinguisher is unobstructed and visible.
  • The operating instructions of each extinguisher are clean and legible and face outwards.
  • Each extinguisher has not been operated and is not obviously damaged or has any missing parts.
  • The reading of any pressure gauge or indicator fitted to an extinguisher is within operational and safety limits.
  • Firefighting equipment’s shall be inspected visually at least once a month to determine that they are fully charged and operable.
  • To verify the records for annual maintenance checks of mechanical parts, the amount and condition of extinguishing agent and expellant, and the condition of the hose, nozzle, and vessel to determine that the fire extinguishers will operate effectively
  • Water pipes, valves, outlets, hydrants, and hoses that are part of the mine's firefighting system shall be visually inspected at least once every three months for damage or deterioration and use-tested at least once every twelve months to determine that they remain functional
  • Fire suppression systems shall be inspected at least once every twelve months.
  • To inspect the efficiency of pipes, fittings, hangers, and Seismic Braces.
  • Testing of dry Pipe Sprinklers.
  • To test the fire pump operation during fire system.
  • To inspect the arrangement of water supply to pump suction.
  • The seals and tamper indicators of each extinguisher are not broken or missing.
  • To verify System Testing Records to ensure NFPA compliance.
  • To check the system start by dropping water pressure, running alarm, start by power failure, over speed Shutdown (Diesel), battery-failure alarm etc.

Why to do Electrical Visual Inspections

  • Electrical leads are checked for damage, repairs and also that they are not in a position where they can be damaged.
  • All electrical devices are working.
  • Single line wires are used in electrical DB’s.
  • Have cables been installed in vulnerable situations?
  • Have cables, enclosures and accessories been fixed securely?
  • Are earthing clamps to BS 951 standards and correctly labelled?
  • Are the cables of different voltage bands segregated? Low voltage, separated extra low voltage (SELV), telephone cables or television aerials should not be fixed together (although they are permitted to cross).
  • Are all cables terminated and all connections tight (no loose ends)?
  • Is there a mixture of protective devices?
  • Are there any damaged cables (perished or cut)?
  • Have all circuits got Circuit Protective Conductors (CPCs)?
  • Are all earthing conductors sleeved?
  • Look to see if the protective devices seem suitable for the size cables that they are protecting.
  • Have all of the circuit conductors been connected in sequence, with phase, neutral and CPC from circuit number 1 being in terminal number 1 – preferably the highest current nearest the main switch?
  • Have any protective devices got multiple conductors in them, are they the correct size (all the same)?
  • Plugs and sockets are intact i.e. not cracked or damaged, with no discoloration or burn marks.
  • Socket outlets are not over loaded.
  • Light sockets and switches are securely fitted with no discoloration or burn marks.
  • Bathroom electrical outlets are at least 3 meters from the edge of a bath or shower cubicle and those electric heaters and boilers are permanently wired. They should not be free standing or portable.
  • Plugs and sockets are intact i.e. not cracked or damaged, with no discoloration or burn marks.
  • There are no visual signs of burning, overheating or damage and no burning smell at the electrical intake position.
  • All fittings i.e. light fittings / sockets / switches / outlets / showers / storage heaters etc. on the premises are tightly secured in their back box, with all screws present.
