# Tragedy in South Garo Hills as Toxic Fumes Claim Lives of Four Construction Laborers from Assam > Four construction workers from Assam lost their lives due to toxic gas inhalation while working on a septic tank at a residence in Meghalaya's South Garo Hills district. **Type:** article · **Category:** Tripura · **Published:** 2026-09-28 · **Source:** TrendKia **Canonical:** https://trendkia.com/en/tripura/meghalaya-ke-south-garo-hills-men-jaharili-gaisa-se-assam-ke-chara-nirmana-shramikon-ki-dardanaka-mauta-39821 · **Language:** English **Tags:** Meghalaya, South Garo Hills, Assam, Septic Tank Accident, Toxic Gas, Laborers Death A routine construction project in Meghalaya turned tragic when four laborers hailing from neighboring Assam lost their lives after breathing in toxic fumes inside an underground septic tank. The incident occurred on Sunday afternoon in Rangdokram village, located in the South Garo Hills district. ## The Sequence of Events The laborers were employed at the residence of Sebastian Ch. Sangma. At approximately 3 pm, the workers were performing their duties when two of them went to open the cover of a newly built septic tank. Immediately after lifting the lid, both workers collapsed due to the sudden emission of poisonous gases. Seeing their colleagues fall, the other two laborers rushed into the area in an attempt to save them. However, they were also quickly overpowered by the lethal fumes and fell unconscious. ## A Demanding Rescue Effort Local authorities, including the police and personnel from the Fire and Emergency Services, arrived at the scene shortly after being alerted. They immediately initiated a rescue operation, which proved to be highly challenging. Because the septic tank was built underground, rescuers could not easily access the victims. The emergency team had to dig up the soil surrounding the structure to create a passage to reach the trapped men. During this rescue attempt, the environment inside was so hazardous that two firefighters also lost consciousness and required immediate medical treatment. ## Identity of the Deceased Despite the efforts of the emergency responders, all four workers could not be saved and succumbed to gas poisoning. Authorities have identified the deceased individuals, who were all residents of the South Salmara-Mankachar district in Assam. The victims are Mofidur Rohman (34) from Diara, Purandiara; Ajiyer Rahman (41) from Chengurchar, Purandiara; Ismail Hussain (20) from Chomrashali, Kalapani; and Rakib Hussain (22) from Boalia, Radhamadhab Hat. ## Lack of Ventilation Suspected Preliminary observations suggest that the newly constructed septic tank lacked an adequate gas outlet or a soak pit. The absence of proper ventilation is believed to have led to a high concentration of hazardous gases, such as methane and hydrogen sulphide, within the confined underground space. While these gases are known to accumulate rapidly in unventilated chambers, an official investigation has been launched to determine the precise cause of death. ## What this means for you This tragic incident underscores the critical importance of safety protocols in construction, directly affecting workers and property owners involved in sanitation projects. - **Across India:** Property owners must ensure all new septic tanks are built with standard gas vents. Failing to do so can lead to severe legal liabilities and unsafe work environments. - **For Construction Workers:** Laborers must avoid entering enclosed spaces without proper gas detectors or masks. Employers are responsible for providing this safety gear under labor regulations. - **In Meghalaya and Assam:** Local administrations in South Garo Hills and Mankachar may tighten safety inspections for ongoing private constructions. Residents must comply with standard municipal guidelines to prevent such toxic gas build-ups. - **Emergency Procedures:** Bystanders should never enter a septic tank to rescue collapsed workers without safety equipment. They must immediately contact local fire departments instead of risking their own lives. ## Why this happened The tragedy was caused by the accumulation of deadly gases in an unventilated septic tank. When the workers opened the lid, they were immediately exposed to a concentrated wave of these toxic fumes. - **Lack of Ventilation:** The newly constructed septic tank reportedly lacked a proper gas outlet or soak pit. This structural deficiency prevented the natural escape of hazardous gases. - **Toxic Gas Accumulation:** In closed, damp spaces like septic tanks, organic decomposition produces highly toxic gases such as hydrogen sulphide and methane. These gases can quickly displace oxygen and lead to fatal asphyxiation. - **Failed Rescue Attempt:** The lack of awareness and proper protective gear led the other two workers to enter the tank in a desperate rescue bid. They fell victim to the same fumes, which is a common pattern in septic tank accidents. ## Questions & Answers ### 1. Where did this accident take place?
