When Infrastructure Fails: A Forensic Investigation into a Chimney Collapse in Penang

In the industrial corridors of Penang, Malaysia, a sudden structural failure can lead to significant operational downtime and safety hazards. This case study examines the technical root cause analysis (RCA) of a chimney collapse at a mattress manufacturing facility during a severe thunderstorm. Our forensic engineering team was commissioned to determine whether the failure was […]

FLOOD RESTORATION IN ASIA: Why the First 48 Hours Decide Everything

When a flood hits an industrial facility, most people look at the water and assume the water is the problem.But after decades of responding to monsoon-season disasters across Malaysia, Singapore, Vietnam, Indonesia, and the Philippines, we’ve learned something very different: A facility that could be 90% restorable on Day 1 can easily become a total […]

Seek Fire and Explosion Investigation Services by Approved Group International

In the unnerving aftermath of a conflagration or detonation, discerning the root cause is imperative. These unsettling events transpire with alarming frequency across residential, commercial, and industrial domains, necessitating thorough forensic investigation. Approved Group International (AGI) excels in providing an exceptional fire and explosion investigation service that adheres to the stringent standards set by the […]

ENHANCING COMMUNITY SAFETY AGAINST INCENDIARY FIRES: PREVENTION AND AWARENESS

Incendiary fires, those deliberately set to cause damage or harm, pose a significant threat to community safety. Not only can they result in the loss of property and lives, but they can also create widespread fear and disruption. Preventing these fires requires a community-centric approach focused on education, vigilance, and the implementation of effective safety […]

Vehicle Collision Investigation - Motorcycle and Motorcar

At about 1740 hours on Sunday, 29 September 2013, a motorcycle (hereinafter referred to as The Motorcycle) driven by Mr. X collided with a motorcar (hereinafter referred to as The Car) driven by Ms A was reported to have occurred at the traffic light junction of Jalan Semarak and the slip road onto the West-bound lanes of the ‘Duta-Ulu Klang Expressway’.

Failure of a Kiln Burner at a Cement Plant

The operation for Kiln 3 at a cement plant was stopped at 11.25pm due to red spot (brick failure). Investigation indicates that the air channel pipe was "missing", which resulted in a distorted flame shape. This is because the primary function of the air channel pipe is said to shape the flame and swirl the air whilst introducing the coal dust, to enable efficient combustion.

Water Damage Assessment

Water, as simple as it sounds, can cause hundreds to thousands worth of damage. Various items can be damaged by water such as wood furniture, carpets, electronics and appliances in commercial buildings or residential households. Water damage can originate from different sources such as broken or leaking pipes, clogged pipes, water pump failure, natural disasters such as flood and rain. Insurance policy normally would cover the cost associated with water damage. Hence, water damage assessment is important to verify the water-affected items as well as to determine the severity of the damage.

Steam Turbine Failure Investigation

At about 0930 hours on Monday, 13 January 2014, an explosion occurred at a steam turbine generator.

Crane Failure Investigation

At approximately 0840 hours on Thursday, 1 August 2013, it was reported that hoist crane No '2' had fallen after hoisting a set of screws. Further inspection conducted on the hoist crane revealed that one of the planetary wheel gears inside the gearbox had fractured. No casualty was reported at that time as the mill was not in production.

Seeing is Believing – Infrared Thermography

Approved’s comprehensive reports pinpoints the exact cause of problems that threaten the integrity of a company’s electrical and mechanical systems and the identification of damage to water systems. Our thermographers are trained, certified and experienced in thermal infrared scanning.

Collision Damage Classification

Collision Damage Classification (CDC, per SAE MAR80 J224) is an excellent tool to provide a clear and concise description to the principal direction of force (PDoF) onto a motor vehicle during a vehicular accident investigation and reconstruction.

The standard was developed by the federal United States government to simplify the description of damage, where the direction of PDoF at point of impact (POI), vehicle deformation location, general type of collision, and damage scale are entailed and coded by numbers and letters.

Fire Debris Collection for Instrumental Analysis

Persistence of ignitable liquid residues at fire scenes can challenge the most experienced fire investigator. The recovery of Ignitable liquid residue requires knowledge, experience, skill and a certain amount of luck. John has recently presented a paper titled "Fire Debris Collection for Instrumental Analysis" at "The Evidence Conference", delivered in Washington DC and this article aims to provide a summary of his paper.

Dehumidification Process

The basic functional principle of drying dehumidifier is really quite simple. A fan draws in humid air and carries it through a refrigerated evaporator. The air is cooled well below its dew point. The water condenses on the cold surface of the evaporator and drips into a water container or is led directly to a drain. Then the cold dry air continues through a hot condenser which heats it up and returns it to the room to pick up new humidity. This procedure is continued until the desired condition is achieved.
