More Oversight Makes Cement Plants Less Safe

Published

Dijam Panigrahi makes a counterintuitive but data-backed argument that routing every sensor alert through human approval does not make cement plants safer.

India’s cement industry has spent the last two years wiring kilns, mills and coolers with sensors and automated control systems, and the safety case for doing so is strong on paper. Contract workers still make up the majority of the industry’s workforce, and fatal accidents remain a recurring problem. The Indian National Cement Workers Federation has noted that around 83 per cent of workers in the sector hold precarious positions, a fact that resurfaced after an oxygen cylinder explosion killed three contract workers at a plant in Chhattisgarh.
Industry tallies compiled by IndustriALL found cement plants recorded at least seventeen accidents in one year with 21 workers killed, and ten accidents the following year with nine killed, most of them contract staff. Automated monitoring, in theory, closes that gap. A sensor never gets complacent and never skips a check because a shift is short staffed.
However, plants that respond by routing every anomaly reading to a person for approval are quietly building a system that fails the same way understaffing does. When operators receive dozens of flagged deviations a shift, most of them minor, they learn a simple lesson: the fastest way through the queue is to approve without reading closely. The safety benefit disappears, not because the technology failed, but because the humans supervising it adapted to the volume.

Why alerts get ignored
A study cited by manufacturing technology publisher Applied SmartFactory found more than 95 per cent of alarms in a semiconductor fab were low priority, and only about 4 per cent ever triggered an action, with just 100 out of 5,000 alarms accounting for 70 per cent of all alarm activity. The mechanism is the same whether the trigger is a vibration sensor or an AI model flagging a kiln temperature swing. Once the ratio of noise to signal crosses a threshold, workers stop treating the system as a decision aid and start treating it as a formality to clear.
The scale of AI deployment underway makes this more than a theoretical risk. Stanford’s 2026 AI Index Report found organisational adoption of AI has reached 88 per cent, even as documented AI incidents rose to 362 in 2025, up sharply from 233 the year before, according to analysis of the report. The Index also found only about a third of organisations have adopted a formal governance framework, with NIST’s AI Risk Management Framework cited by 33 per cent and ISO/IEC 42001 cited by 36 per cent.
Most manufacturers are deploying monitoring systems faster than they are building the judgment for when a flagged event actually needs a person’s attention. In India, plants run by JK Cement have begun pairing CCTV feeds with AI to define safe zones around heavy machinery, a promising direction that still depends on operators trusting and reading the alerts the system generates.

A three-tier model for cement plant
The fix is not less monitoring or more monitoring. It is classifying decisions by risk and by novelty, rather than treating human oversight as a single switch that is either on or off. A workable model sorts factory floor events into three tiers.
The first tier, proceed, covers deviations the plant has seen before that fall within known safe bounds, such as a kiln feed rate adjustment within an established range. These should run without a stop for approval, because routing them to a person only trains that person to click through.
The second tier, pause, covers events that are unusual but not yet dangerous, such as a vibration reading trending toward a limit or a fuel blend shifting outside its typical mix. These warrant a brief human check before the system proceeds, giving an operator the chance to apply judgment the model does not yet have.
The third tier, escalate, covers events that are both high risk and unfamiliar, such as a pressure reading combined with a temperature spike that has no close precedent in the plant’s history. These should stop the process entirely and require a decision from someone with the authority to shut down a line.

Who should set the threshold
Where these tiers get drawn matters as much as the framework itself. Threshold setting is frequently handed to the vendor supplying the monitoring software or to a plant’s IT department, both of which understand the technology but not the specific tolerances of a given kiln, mill or line. Operations staff, who know that a particular grinding unit runs hotter under monsoon humidity or that a calciner behaves differently after a refractory reline, are better positioned to calibrate what counts as routine on their own equipment.
Handing threshold ownership to operations does not remove IT or vendors from the process, but it puts the calibration decision closest to the people who live with its consequences on the floor.

Signals that oversight is actually working
A few concrete indicators reveal whether a monitoring setup is functioning as intended or simply providing the appearance of safety. The escalation rate over time is the first: a rate that stays flat or climbs slowly as operations mature is healthy, while one that spikes and then falls sharply often means operators have started overriding the system rather than engaging with it. Time to resolution is the second: escalations that take progressively longer to close suggest fatigue or confusion about ownership, not diligence. The third, and most telling, is how accurate the system’s own uncertainty estimates turn out to be, meaning whether events flagged as high risk actually correlated with real incidents, and whether events waved through stayed incident free. A system whose escalations do not track with actual outcomes trains operators toward the same complacency that unmonitored equipment produces.
None of this argues against automation in Indian cement manufacturing, where a labor structure built on contract work and a track record of serious accidents make better monitoring an urgent need. It argues for treating human oversight as a design problem with three distinct settings, rather than a single
dial turned up whenever a plant wants to look safer on paper.

The Assam Cabinet has approved an investment of Rs. 110 bn by JK Lakshmi Cement for a clinker manufacturing unit and four associated cement grinding units in the state. Chief Minister Himanta Biswa Sarma announced the decision on 24 September 2026, along with approvals covering wetland restoration and industrial support.

The proposed cement investment is expected to generate around 2,000 direct jobs. The project forms part of the state government’s latest measures to attract manufacturing activity and strengthen industrial infrastructure. The Cabinet also approved a State Capital Investment Subsidy for eligible manufacturing units covered by the substantive provisions of the Uttar Poorva Transformative Industrialization Scheme, or UNNATI, 2024.

The subsidy will apply to units that qualified under the scheme but were unable to secure registration by the extended deadline of 30 September 2026. The measure is intended to support eligible businesses that missed the registration process while continuing to meet the scheme’s substantive requirements.

The Cabinet also cleared an Asian Development Bank (ADB)-funded project for the restoration and rehabilitation of at least 102 derelict community beels across Assam. The ADB loan component is Rs. 6.38 bn, while the Assam government’s contribution will be Rs. 1.59 bn.

In another decision, the Cabinet approved a rent-based or pro bono arrangement for constructing a laboratory and ancillary infrastructure for the Spices Board under the Ministry of Commerce and Industry. The facility will be built at Ulubari in Guwahati, with the Agriculture Department coordinating with the Public Works Department (Buildings) to construct it according to designs and specifications provided by the board.

JSW Cement has received a show-cause notice proposing a Goods and Services Tax (GST) demand of Rs. 2.3 bn, along with applicable interest and a 10 per cent penalty, over an alleged incorrect classification of transactions. The notice was issued by the Additional Commissioner of Central Tax, Belagavi Audit Commissionerate, on September 24, 2026.

The proposed demand relates to the period from April 2022 to March 2024 and has been issued under Section 73 of the Central Goods and Services Tax (CGST) Act, 2017. The company disclosed the notice in a filing with the stock exchanges and said the matter involved an alleged short payment of GST.

The proposed amount comprises Integrated GST (IGST) of Rs. 1.22 bn, Central GST (CGST) of Rs. 540.5 mn and State GST (SGST) of Rs. 540.5 mn. The department has also cited alleged contraventions of Sections 9, 37 and 39 of the CGST Act, with interest proposed under Section 50 and the penalty under Section 73.

JSW Cement said the financial impact of the notice would be limited to the proposed tax demand, applicable interest and penalty. However, it assessed that the matter would not have a material impact on the company. The cement manufacturer is preparing its reply to the show-cause notice.

The notice was issued to JSW Cement, which is part of the Sajjan Jindal-promoted JSW Group. The company reiterated that the total proposed GST demand stood at Rs. 2.3 bn, excluding the applicable interest and 10 per cent penalty, and that the proceedings remained at the show-cause stage.

Shares of JSW Cement ended at Rs. 115.65 on the BSE on Thursday, down Rs. 2.60, or 2.20 per cent, from the previous close. The stock movement came as the company disclosed the proposed tax demand and its intention to respond to the department’s notice.

Montra Electric and Wonder Cement have begun commercial operation of a 250-vehicle deployment of Rhino 5538 EV 4×2 tractor-trailers on an electric freight corridor linking Rajasthan with ports in Gujarat. The companies said the fleet is being used for regular cement logistics rather than a limited pilot, making it one of the largest heavy-duty electric truck deployments by an Indian industrial company.

An initial 30 trucks were introduced from Wonder Cement’s plant in Nimbahera, Rajasthan, in July 2026. They are hauling full payloads on daily routes between Nimbahera and Dahej Port and between Nimbahera and Tuna Port, covering approximately 1,450 km across Rajasthan, Madhya Pradesh, Maharashtra and Gujarat. The vehicles operate to schedules comparable with those of the company’s conventional diesel fleet.

The corridor is supported by 13 dedicated charging stations positioned to enable long-distance duty cycles within industrial turnaround times. The Rhino 5538 EV is available with a 55 t Gross Combination Weight option and is designed for cement, coal and clinker transport. Its specifications include a 282 kWh lithium iron phosphate battery, a Permanent Magnet Synchronous Motor producing 280 kW and 2,000 Nm of torque, 18 per cent continuous gradeability and a 6-speed Automated Manual Transmission.

The vehicle has a stated range of 198 km under specified test conditions, with one side loaded and the other empty. It can charge from 20 to 100 per cent State of Charge in 60 minutes and is supported by more than 95 per cent assured uptime. Montra Electric and Wonder Cement said the deployment would assess electrification through payload capacity, turnaround performance and daily availability in live freight operations.

Montra Electric said the same operating model could support steel, mining, infrastructure and port haulage, where fixed routes and predictable turnaround windows are common. The company has more than 750 heavy-duty electric vehicles on Indian roads and has covered over 30 mn km across its deployments. Montra Electric operates as the clean mobility arm of the Murugappa Group, with businesses spanning heavy commercial vehicles, smaller commercial vehicles, three-wheelers and electric tractors.
