Human error? Consider human factors

Human error? Consider human factors

When accidents happen, it's tempting to see human error as the cause — the worker made a bad decision, wasn't paying attention, didn't follow the rules. But human error is a symptom of deeper trouble and is just a starting point in an accident investigation. Usually many elements contribute to an accident. Human error is only a label, one that requires exploration.

What's behind human error?

No one goes to work intending to be injured. The decisions and actions that workers take make sense to them at the time given their goals, knowledge, and focus of attention. Every day, workers adapt to changes in their workplace and modify their actions to keep things operational. When an accident happens, the key is to find out how the worker's actions were influenced by different elements in the workplace.

The science of human factors focuses on those elements. Human factors evaluates the interaction between people, workplaces, and management systems — the elements that make up the "workplace system." The human factors approach to an investigation asks why a worker's decision or action made sense to that worker at the time.

Because it is system-based, the human factors approach is a valuable way of looking at the big picture of an accident. Once it's clear what shaped and guided a worker's decisions and actions, steps can be taken to prevent similar accidents from happening.

What happened?

A serviceman was called to a worksite to install new tires on a transport truck. He attached the air supply hose to one tire, positioned the tire on the wheel rim, and left the tire to fill while he did other tasks. He later returned and was preparing to check the tire pressure with a hand-held gauge when the tire exploded off the rim. The explosion caused serious injuries that led to the worker's death.

From a human factors perspective, why did it happen?

The accident happened because the tire was overinflated and the worker was standing nearby when it exploded. The human factors approach asks why the tire was overinflated and why the worker was standing close by.

Several workplace factors led this worker to act as he did. First, the automatic shutoff on the air compressor was set to 175 psi, well above the 100 psi needed to inflate the truck tires. Second, the air hose had no inline pressure gauge, so the worker had to check the pressure up close with a hand-held gauge. Third, there was no cage or other restraining device around the tire to hold it in place if it exploded.

Also, certain management factors influenced the worker's behaviour. Management had not given him appropriate equipment, adequate training, or safe work procedures.

Considering all of these factors, the worker acted in ways that made sense to him. His actions were based on the resources and knowledge available to him as he worked to fulfill the goal of changing the tire.

Kesalahan manusia? Mempertimbangkan faktor-faktor manusia Ketika kecelakaan terjadi, itu tergoda untuk melihat kesalahan manusia sebagai penyebab - pekerja membuat keputusan yang buruk, tidak memperhatikan, tidak mengikuti aturan. Tapi kesalahan manusia adalah gejala dari masalah yang lebih dalam dan hanya titik awal dalam penyelidikan kecelakaan. Biasanya banyak elemen berkontribusi kecelakaan. Kesalahan manusia hanya label, yang membutuhkan eksplorasi. Ada apa di balik kesalahan manusia? Tidak ada yang pergi bekerja berniat untuk terluka. Keputusan dan tindakan yang pekerja mengambil masuk akal bagi mereka pada waktu tertentu tujuan mereka, pengetahuan, dan fokus perhatian. Setiap hari, pekerja beradaptasi dengan perubahan di tempat kerja mereka dan memodifikasi tindakan mereka untuk menjaga hal-hal operasional. Ketika kecelakaan terjadi, kuncinya adalah untuk mengetahui bagaimana tindakan pekerja dipengaruhi oleh unsur-unsur yang berbeda di tempat kerja. Ilmu faktor manusia berfokus pada unsur-unsur. Faktor manusia mengevaluasi interaksi antara orang-orang, tempat kerja, dan sistem manajemen - ". Sistem kerja" unsur-unsur yang membentuk Faktor manusia pendekatan untuk penyelidikan bertanya mengapa keputusan pekerja atau tindakan masuk akal untuk pekerja yang pada saat itu. Karena berbasis sistem, pendekatan faktor manusia adalah cara yang berharga melihat gambaran besar dari kecelakaan. Setelah itu jelas apa dibentuk dan dipandu keputusan dan tindakan seorang pekerja, langkah yang dapat diambil untuk mencegah kecelakaan serupa terjadi. Apa yang terjadi? A reparasi dipanggil ke tempat kerja untuk menginstal ban baru pada truk transportasi. Dia memasang selang pasokan udara ke satu ban, posisi ban pada pelek roda, dan meninggalkan ban untuk mengisi sementara dia melakukan tugas-tugas lain. Ia kemudian kembali dan sedang mempersiapkan untuk memeriksa tekanan ban dengan ukuran genggam ketika ban meledak dari RIM. Ledakan itu menyebabkan luka serius yang menyebabkan kematian pekerja. Dari perspektif faktor manusia, mengapa hal itu bisa terjadi? Kecelakaan itu terjadi karena ban adalah overinflated dan pekerja berdiri di dekatnya ketika meledak. Pendekatan faktor manusia bertanya mengapa ban adalah overinflated dan mengapa pekerja berdiri dekat. Beberapa faktor tempat kerja menyebabkan pekerja ini bertindak seperti dia. Pertama, penutup otomatis pada kompresor udara ditetapkan untuk 175 psi, jauh di atas 100 psi dibutuhkan untuk mengembang ban truk. Kedua, selang udara tidak inline pengukur tekanan, sehingga pekerja harus memeriksa tekanan dekat dengan pengukur genggam. Ketiga, tidak ada kandang atau perangkat penahanan lain di sekitar ban untuk menahannya di tempat jika meledak. Juga, faktor manajemen tertentu mempengaruhi perilaku pekerja. Manajemen tidak memberinya peralatan yang sesuai, pelatihan yang memadai, atau prosedur kerja yang aman. Mengingat semua faktor ini, pekerja bertindak dengan cara yang masuk akal baginya. Tindakannya didasarkan pada sumber daya dan pengetahuan yang tersedia baginya saat ia bekerja untuk memenuhi tujuan mengubah ban. Interaksi faktor manusia
