Block Masonry Safety: JSA Checklist & Guide

• First, competent persons (permit receivers) must solely execute the permit.

• Furthermore, operators must verify the exact location before signing the work permit.

• Consequently, issuers and receivers must conduct site inspections to identify hazards before signing the work permit.

• Additionally, supervisors and receivers must communicate properly before applying for the work permit.

• Heavy and awkward size of materials.

• Improper storage of materials.

• Miscommunication where to put the materials.

• Personnel back injury.

• Skin irritation.

• Environmental issue.

• First, all workers must attend a safety toolbox meeting prior to starting any activity to discuss actual hazards.

• Furthermore, workers must use proper methods and techniques for material handling.

• Consequently, personnel must not attempt manual lifts if materials are too heavy.

• Additionally, teams must use proper equipment if necessary.

• Moreover, workers must wear proper personal protective equipment, like dust masks, safety shoes, helmets, gloves, and safety glasses.

• Subsequently, crews must secure materials properly and organize them.

• Next, supervisors must install barricades and signboards.

• Therefore, management must approve the material storage location prior to delivery on site.

• Finally, good communication between crew members must reinforce individual awareness of real and potential hazards.

• Exposed cable.

• Not inspected hand tools.

• Unwanted material on access.

• Electrical shock.

• Bodily injury.

• Slip, trip and fall.

• First, management must provide a permit to work before starting any activity.

• Furthermore, supervisors must properly inspect and color-code tools and equipment.

• Consequently, workers must use insulated power tools.

• Additionally, personnel must wear appropriate hand gloves to avoid electrical shock.

• Moreover, inspectors must complete inspections prior to starting the activity.

• Subsequently, workers must never use homemade hand tools.

• Therefore, crews must remove all waste and scrap material from the area.

• Next, teams must not store material near access points.

• Finally, supervisors must provide barricades and signages to temporary material storage areas.

• Spark projectile.

• Excessive noise.

• Inhalation of dust or particulate.

• Unforeseen projectile of cracked disk.

• Direct contact to cement.

• Face & eye injury.

• Skin burn.

• Fire.

• Deafness.

• Suffocation and Asphyxia.

• Cut injury and Bodily damage.

• Skin and Eye irritation.

• First, workers must maintain proper positioning while doing the activity.

• Furthermore, personnel must always use proper eye protection.

• Consequently, operators must wear leather gloves, long-sleeved shirts, and long pants.

• Additionally, crews must remove combustible material near the activity.

• Moreover, teams must provide fire extinguishers and fire blankets for cutting activities.

• Subsequently, workers must use earplugs while doing grinding and cutting works.

• Therefore, management must provide proper ventilation to direct or collect dust.

• Next, operators must wear the appropriate respirator or N95 dust mask.

• Specifically, workers must use only disks that are appropriate to the grinder.

• Furthermore, inspectors must verify the RPM of the disk is higher than the machine.

• Additionally, teams must provide proper machine guarding.

• Moreover, management must provide clean water to the area.

• Consequently, supervisors must include the location of the nearest shower or eye wash station in the toolbox meeting.

• Finally, management must make MSDS available at the area of activity.

• Excessive dust from the cement.

• Heat produce on grinding.

• Direct contact to cement.

• Working at elevated area / scaffolding / Man lift.

• Asphyxia and Suffocation.

• Fire.

• Skin and Eye irritation.

• Falling of material and personnel.

• First, teams must provide blowers to the area to reduce dust accumulation.

• Furthermore, workers must wear proper N95 dust masks.

• Consequently, management must provide water spray or fire extinguishers.

• Additionally, supervisors must provide fire watches who undergo proper training.

• Moreover, personnel must remove all combustible material from the area.

• Subsequently, operators must inspect power tools prior to starting the activity.

• Therefore, workers must use proper PPE such as clothing and safety glasses.

• Next, all personnel must undergo working at heights training.

• Specifically, workers must inspect the scaffold tag before using it.

• Furthermore, personnel must immediately stop using defective scaffolds and call a scaffold inspector.

• Additionally, workers must always use full body harnesses and do 100% tie off.

• Moreover, users must check the anchorage point before utilizing it.

• Consequently, crews must equip all tools with retaining strings.

• Subsequently, personnel must not overreach outside the guard rails of the scaffold.

• Therefore, operators must lock the wheels of mobile scaffolds when using them.

• Next, management must provide flagmen when using man lifts.

• Finally, teams must barricade the area of activity to prevent people from crossing.

• Housekeeping and water disposal.

• Unwanted/ excess material.

• Miss communication & miss understanding.

• Environmental issue.

• Slip, trip and fall.

• First, management must provide temporary material storage to the site to avoid scattering.

• Furthermore, crews must clear unwanted materials from the site from time to time.

• Consequently, personnel must clean the job area after finishing the job.

• Additionally, workers must return excess material to the store.

• Moreover, teams must keep the working area in a high standard of housekeeping.

• Subsequently, personnel must keep refuse in designated bins.

• Therefore, site managers must keep emergency routes clear of any obstruction or closure.

• Next, nobody must run; everyone must calmly but quickly approach the nearest safe assembly area.

• Finally, supervisors must conduct a headcount and wait for further instructions.
