Construction Waterproofing Safety: JSA Guidelines

Miscommunication

Loss of work

• First, designate a competent permit receiver to strictly handle the permit .

• Next, verify the exact location prior to signing the work permit .

• Additionally, conduct a mandatory toolbox meeting prior to starting the activity .

• Finally, mandate that a competent equipment inspector complete the initial crane inspection before permit sign-off.

Over speeding

Manual handling

Collision with other vehicle/structure

Muscular strain, Back issue

• First, secure a permit to work before starting any material movement .

• Furthermore, prohibit the operation or movement of equipment without an active flagman

• Specifically, train the flagman adequately for site operations .

• Next, inspect the equipment and verify its back alarm system thoroughly .

• Additionally, install proper barricades around the primary activity area .

• Moreover, apply proper methods and techniques for all material handling operations .

• Consequently, utilize mechanical lifting equipment for heavy materials to prevent strain .

• Therefore, execute proper stretching, lifting, bending, and moving techniques continuously .

• Specifically, avoid storing paint materials near high-temperature conditions .

• Finally, strictly prohibit hot work activities near painting areas and provide local MSDS availability.

Direct contact to bitumen paint

Skin injury

• First, announce the nearest eye wash station location during the toolbox meeting .

• Furthermore, equip workers with appropriate PPE, including suits, boots, goggles, and masks .

• Next, instruct workers to wash their hands and face routinely, especially before eating, drinking, or smoking .

• Additionally, mandate the vacuuming or removal of contaminated work clothes before breaks .

• Moreover, require the use of proper hand gloves during all painting tasks .

• Finally, ensure all involved workers undergo formal Chemical Handling training.

Working near open hole / pit

USE of LPG tank/ Open Flame

Poor illumination

Exposure to direct sunlight

Fall from height

Fire produced on torch supplied

Trip and fall

Failure to provide sunshades protection

• First, maintain three-point contact while facing the ladder at all times .

• Furthermore, install specific ladders and temporary facilities strictly according to safety regulations .

• Next, deploy only trained and certified workers for these tasks .

• Additionally, enforce ladder safety by keeping hands free of materials during ascent and descent .

• Specifically, obtain a hot work permit before igniting any equipment .

• Moreover, assign only competent personnel to handle the waterproofing torch .

• Consequently, maintain a trained fire watchman on-site continuously .

• Therefore, position active fire extinguishers directly at the workplace .

• Furthermore, enforce continuous, proper supervision across the site .

• Next, mandate appropriate hand gloves to prevent burn injuries .

• Additionally, secure all cylinders firmly in an upright direction .

• Specifically, remove LPG cylinders from the site and return them to the store post-activity .

• Moreover, utilize only inspected equipment bearing valid color-coding tags .

• Consequently, eliminate all potential ignition sources from the immediate area .

• Therefore, install highly visible ‘no smoking’ signage .

• Furthermore, install proper lighting around the site and workplace access paths .

• Next, mandate clear safety glasses inside buildings or dark zones .

• Additionally, supply sufficient cool water strictly within the work area .

• Moreover, rotate shifts routinely for workers engaged in heavy tasks .

• Finally, erect temporary rest shelters to mitigate heat exposure.

Live areas

LOTO of hazardous energy sources (hot water, steam, gas, oil)

Electrocution

Slip, trip and fall

Burn

Explosion

• First, confirm workers hold valid LOTO training and commissioning permits .

• Furthermore, prohibit work entirely in commissioning areas marked with blue and white barricades .

• Next, lock out, tag out, and verify the isolation of all hazardous energy sources .

• Specifically, forbid any attempts to alter equipment tagged with “Danger” or “Do not operate” labels .

• Additionally, mandate hand gloves at all times to prevent pinch point and moving machinery injuries .

• Moreover, restrict entry into energized areas without prior authorization from the HSE department .

• Consequently, enforce strict coordination between the LOTO coordinator, job supervisor, and safety personnel .

• Therefore, strictly prohibit drawing power supplies from energized panel boards .

• Finally, execute mandatory gas testing before initiating any hot work.

High Volatile Organic Compounds (VOC) emission

Confined space entry

Asphyxiation

Toxic inhalation

• First, mandate continuous mechanical ventilation when applying primers and bitumen in basements or tanks.

• Furthermore, conduct pre-entry gas testing to ensure oxygen levels remain between 19.5% and 23.5%.

• Next, require the use of active organic vapor respirator cartridges for all application personnel.

• Finally, station a dedicated hole-watch attendant immediately outside any confined space entry points.
